Newly hatched chicks have limited immunity and body temperature regulation, so they require close monitoring during the first days of life.<\/figcaption><\/figure>\n

Disease prevention for newly hatched chicks begins with understanding their immature immune system, limited ability to regulate body temperature, and low tolerance to environmental stress.<\/p>\n

This is why the first 2 weeks after hatching \u2014 especially the first 7 days \u2014 are often considered a high-risk period for losses in the production cycle. In practical farming, chicks may become weak or die quickly if the brooding area is not warm enough, drinking water is not clean, litter is damp, feed is unsuitable, or chick quality is not assured.<\/span><\/p>\n

However, many cases of early chick mortality or poor growth can be significantly reduced if farmers set up the right care process before the chicks arrive.<\/span><\/p>\n

Disease prevention for newly hatched chicks should not start with veterinary medicines. It should begin with basic management: a warm brooding area, clean drinking water, suitable feed, dry litter, proper hygiene, and flock observation several times a day. Vaccines and veterinary medicines are only effective when used at the right time, using the right product, and according to veterinary advice or the manufacturer\u2019s instructions.<\/span><\/p>\n

This article explains disease prevention for newly hatched chicks throughout the first 14 days, with practical care steps, monitoring checklists, and answers to common questions.<\/p>\n

Quick Summary<\/b><\/h2>\n
    \n
  • Chicks are highly vulnerable to disease during the first 7 days because their immune system is still immature. Keeping them warm, providing clean water, and considering electrolyte supplementation should be prioritized. The vaccination schedule should be arranged according to veterinary advice \u2014 it should not be skipped or adjusted without guidance.<\/span><\/li>\n
  • Three key factors strongly affect survival rate: brooding environment, nutrition and water intake, and proactive disease prevention. Missing any one of these factors often increases the risk of losses.<\/span><\/li>\n
  • A reference brooding temperature is around 33\u201335\u00b0C during the first 3 days, then gradually reduced by week. Flock behavior is the most accurate way to assess the actual temperature experienced by chicks.<\/span><\/li>\n
  • Vaccination schedules and preventive medicine use should be discussed and confirmed with a local veterinarian before implementation.<\/span><\/li>\n

    Why Is Disease Prevention for Newly Hatched Chicks Critical During the First 2 Weeks?<\/h2>\n

    Common Diseases and Causes of Early Mortality in the First Week<\/b><\/h3>\n

    From hatching to around days 7\u201310, chicks are transitioning from nutrients provided by the egg yolk to external feed and drinking water. During this period, the digestive system is not yet stable, the respiratory system is easily affected, and the ability to resist pathogens remains very limited.<\/span><\/p>\n

    Common health issues in the first week include:<\/span><\/p>\n

      \n
    • Omphalitis:<\/b> This occurs when the navel has not fully healed and becomes infected through a damp, dirty environment or during the hatching process.<\/span><\/li>\n
    • Pullorum disease:<\/b> This may be related to <\/span>Salmonella pullorum<\/span><\/i>, with common signs such as white droppings, pasty vent, loss of appetite, rapid weakening, and a high risk of death in chicks. However, dropping color is only an initial indicator. Veterinary assessment or appropriate testing is needed to confirm the cause, because diarrhea in chicks may result from many factors, including cold stress, dirty water, poor-quality feed, transport stress, or bacterial infection.<\/span><\/li>\n
    • Chronic respiratory disease (CRD) and respiratory signs such as wheezing or gasping:<\/b> These may be related to pathogens and often become more serious when the brooding area is exposed to drafts, dampness, dirty litter, high ammonia levels, or excessive stocking density. When many chicks show signs such as breathing difficulty, wheezing, sneezing, or loss of appetite, farmers should isolate affected chicks and contact a veterinarian for cause assessment.<\/span><\/li>\n
    • Newcastle disease and Gumboro disease:<\/b> These are dangerous viral diseases that may affect chicks, especially in areas where the diseases are present and where the flock is not vaccinated or is vaccinated improperly. Gumboro often causes more noticeable losses at later stages, commonly from 3 weeks of age onward depending on maternal antibody levels. Marek\u2019s disease also usually appears later than the first week. During the first week, omphalitis, early bacterial infection, and chick quality issues often play a more significant role.<\/span><\/li>\n
    • Death due to cold or heat stress:<\/b> This is not a disease, but it is a very common cause of early mortality in small-scale farms that have not yet controlled brooding temperature properly.<\/span><\/li>\n<\/ul>\n

      Most of the causes above can be proactively prevented to a certain extent. Their shared feature is that they appear quickly, progress quickly, and cause major losses if detected late.<\/span><\/p>\n

      Three Key Factors Affecting Chick Survival Rate: Environment \u2013 Nutrition \u2013 Proactive Disease Prevention<\/b><\/h3>\n

      Disease prevention for newly hatched chicks during the first 2 weeks should focus on three key factors:<\/p>\n

        \n
      • Environment:<\/b> Stable temperature, moderate humidity, no drafts, and clean, dry litter. This factor has a direct and immediate impact on chick health.<\/span><\/li>\n
      • Nutrition:<\/b> Clean drinking water, feed suitable for each stage, timely electrolyte and vitamin support, and avoidance of damp, moldy, or excessive feed.<\/span><\/li>\n
      • Proactive disease prevention:<\/b> Vaccination schedules, hygiene and disinfection, and control of people and objects entering the house. These measures are not intended to be applied only when chicks are already sick; they should be implemented early and continuously.<\/span><\/li>\n<\/ul>\n

        These three factors interact with each other. A good environment helps feed digestion become more effective. Adequate nutrition supports better vaccine response. Proactive disease prevention reduces the burden on both the environment and the chicks\u2019 natural resistance.<\/span><\/p>\n

        Brooding Conditions for Disease Prevention for Newly Hatched Chicks<\/h2>\n
        \"Newly
        The brooding area should be cleaned, preheated, and equipped with suitable feeders and drinkers before the chicks arrive.<\/figcaption><\/figure>\n

        Preparing the Brooding Area Before Chicks Arrive: Equipment, Cleaning, and First Disinfection<\/b><\/h3>\n

        The brooding area should be prepared and disinfected at least 48 hours before chicks arrive. Placing chicks into a poultry house that has just been disinfected and still has a strong chemical smell may irritate their respiratory tract.<\/span><\/p>\n

        Preparation checklist:<\/span><\/p>\n

          \n
        • A brooding area or chick house that has been washed, dried, and disinfected.<\/span><\/li>\n
        • Litter, usually new, dry, clean rice husk, around 5\u20138 cm thick.<\/span><\/li>\n
        • Brooder lamps or infrared lamps placed at the correct height to provide suitable heat.<\/span><\/li>\n
        • A thermometer placed low, close to the litter surface, to measure the actual temperature experienced by chicks.<\/span><\/li>\n
        • Drinkers and feeders that have been washed, disinfected, and dried.<\/span><\/li>\n
        • Draft shields if the house is open to wind, or curtains to adjust ventilation.<\/span><\/li>\n
        • For small-scale farms, a circular brooder guard made of metal sheet or plastic with a radius of around 1\u20131.5 m per 100 chicks is usually sufficient to retain heat and prevent chicks from moving into colder areas.<\/span><\/li>\n<\/ul>\n

          Brooding Temperature for Chicks by Stage During the First 2 Weeks and How to Read Flock Behavior<\/b><\/h3>\n

          Temperature is the most important factor during the brooding stage. Chicks still have poor body temperature regulation during the first 2 weeks, so farmers need to actively control brooding temperature and monitor flock response frequently.<\/span><\/p>\n

          The table below is for reference only for common production models. It should be adjusted according to the breeder\u2019s technical recommendations, the actual housing system, and veterinary guidance.<\/span><\/p>\n\n\n\n\n\n\n
          Stage<\/b><\/td>\nReference Temperature Under the Heat Source<\/b><\/td>\nReference Temperature at the Edge of the Brooding Area<\/b><\/td>\n<\/tr>\n
          Days 1\u20133<\/span><\/td>\n33\u201335\u00b0C<\/span><\/td>\n28\u201330\u00b0C<\/span><\/td>\n<\/tr>\n

          However, a thermometer is only a reference tool. Flock behavior is the most practical indicator:<\/span><\/p>\n

            \n
          • Chicks huddle tightly near the heat source and pile on top of each other \u2192 too cold; increase heat or lower the brooder lamp.<\/span><\/li>\n
          • Chicks move far away from the heat source, breathe with open mouths, or spread their wings \u2192 too hot; reduce heat or raise the brooder lamp.<\/span><\/li>\n
          • Chicks are evenly distributed inside the brooder ring, active, and eating and drinking normally \u2192 temperature is suitable.<\/span><\/li>\n<\/ul>\n

            A common mistake is relying only on the thermometer without observing chick behavior, which can lead to temperature adjustments that do not match the actual housing conditions.<\/span><\/p>\n

            Humidity, Ventilation, Draft Prevention, and Lighting for Newly Hatched Chicks<\/b><\/h3>\n

            Humidity:<\/b> A reference range of around 60\u201370% may be used, but it should be adjusted according to house conditions, litter condition, season, and the breeder\u2019s technical recommendations.<\/span><\/p>\n

            If the house is too dry, chicks may experience respiratory irritation or discomfort. If humidity is too high, litter becomes wet more easily, creating conditions for bacteria, mold, and toxic gases to develop.<\/span><\/p>\n

            Ventilation:<\/b> Air should circulate gently, but direct drafts into the brooding area must be avoided.<\/span><\/p>\n

            Drafts are among the key risk factors linked to respiratory problems in chicks during the first week, especially when combined with high stocking density or damp litter.<\/span><\/p>\n

            Lighting:<\/b> Many practical guides recommend almost continuous lighting during the first 3 days, around 23 hours per day, so chicks can easily find feeders and drinkers.<\/span><\/p>\n

            From day 4 onward, lighting may be reduced to around 18\u201320 hours per day. However, this should be adjusted according to breeder guidance, production model, and actual farm conditions.<\/span><\/p>\n

            Stocking Density in the Brooding Area and How to Handle Wet Litter<\/b><\/h3>\n

            Stocking density for chicks during brooding is often recommended at around 20\u201330 chicks\/m\u00b2, depending on breed, open or closed housing systems, and breeder recommendations. Excessive density increases local heat, raises ammonia levels, and increases the risk of respiratory and digestive disease outbreaks.<\/span><\/p>\n

            For litter management:<\/span><\/p>\n

              \n
            • Check litter moisture at least once per day, especially around drinkers.<\/span><\/li>\n
            • When litter becomes wet, caked, or has a strong ammonia smell, loosen it immediately and add dry rice husk on top. Do not leave wet litter overnight.<\/span><\/li>\n
            • Avoid using long straw or damp sawdust as litter for chicks because they are prone to mold and are difficult to turn.<\/span><\/li>\n<\/ul>\n

              Water and Nutrition in Disease Prevention for Newly Hatched Chicks<\/h2>\n
              \"Young
              Clean drinking water should be available as soon as chicks enter the brooding area, with drinkers cleaned and refilled regularly.<\/figcaption><\/figure>\n

              How Soon Should Newly Hatched Chicks Be Given Water and Feed?<\/b><\/h3>\n

              After hatching, chicks may still use part of the nutrients from the egg yolk for the first 1\u20132 days. However, drinking water should be provided immediately when chicks are placed in the brooding area. Farmers should not wait until chicks appear thirsty.<\/span><\/p>\n

              Farmers may spread feed on paper or shallow trays around 3\u20136 hours after chicks have first received water. This stimulates natural feeding behavior and helps the digestive tract start functioning early.<\/span><\/p>\n

              Principles for Clean Drinking Water: Water Type, Water Replacement, Number and Placement of Drinkers<\/b><\/h3>\n
                \n
              • Use clean water with no strong chlorine smell. If tap water is used, it should be left overnight or aerated before being given to chicks.<\/span><\/li>\n
              • During the first 2\u20133 days, electrolytes and vitamins may be added to drinking water according to product label instructions, especially for flocks transported over long distances or showing signs of post-hatch stress. Consult a veterinarian about the appropriate product and dosage.<\/span><\/li>\n
              • Replace water at least twice per day and clean drinkers each time to prevent algae and bacterial buildup.<\/span><\/li>\n
              • As a reference, around one small 1-liter drinker for 50\u201370 chicks may be used, but this should be adjusted so that chicks always have access to clean water at all times.<\/span><\/li>\n
              • Place drinkers near the heat source but not directly under the lamp to prevent rapid evaporation and to reduce the risk of chicks knocking them over while gathering for warmth.<\/span><\/li>\n<\/ul>\n

                Suitable Feed for Chicks During the First 2 Weeks and How to Avoid Waste, Dampness, and Mold<\/b><\/h3>\n

                Use compound feed specifically formulated for chicks, usually labeled \u201cStarter\u201d or \u201c0\u201321 days,\u201d with nutrient levels suitable for the early stage. Do not use feed for older chickens or self-mixed feed that does not ensure balanced nutrition.<\/span><\/p>\n

                Feeding principles:<\/span><\/p>\n

                  \n
                • Spread feed in a thin layer on trays or firm paper during the first 3 days so chicks can easily see and eat it. From day 4 onward, gradually switch to specialized feeders.<\/span><\/li>\n
                • Feed small amounts several times instead of pouring out a large amount at once. Feed left in feeders for too long absorbs moisture, becomes moldy easily, and becomes a source of bacterial contamination.<\/span><\/li>\n
                • Do not use feed that has been stored too long, become clumped, or developed an unusual smell. Moldy or damp feed is a clear risk factor for diarrhea and digestive disorders in chicks.<\/span><\/li>\n<\/ul>\n

                  Electrolytes, Vitamins, Digestive Enzymes, and Probiotics: When to Use and for How Long?<\/b><\/h3>\n
                    \n
                  • Electrolytes:<\/b> These may be considered during the first few days, especially when chicks have been transported over long distances, show signs of stress, or have mild dehydration. Use according to product instructions and veterinary advice. Avoid overdosing or combining multiple products at the same time.<\/span><\/li>\n
                  • Vitamin C or B-complex:<\/b> These may be considered in situations involving stress, poor feed intake, or post-transport recovery, depending on flock condition and product instructions. They should not be used for prolonged periods or combined with many supplements without veterinary advice.<\/span><\/li>\n
                  • Digestive enzymes or probiotics:<\/b> These may be considered when chicks are stressed, changing feed, digesting poorly, or showing mild digestive disturbance. Use according to product instructions. They should not be used mechanically as a routine if the flock is healthy, eating and drinking well, and droppings are normal.<\/span><\/li>\n<\/ul>\n

                    Note:<\/b> Do not mix many products together at the same time without veterinary guidance. Some products may interact or reduce each other\u2019s effectiveness when mixed together. Always check the instructions for each product before combining them.<\/span><\/p>\n
