Chicks are susceptible in the days after hatching, as their digestive systems and immunity are underdeveloped and their ability to regulate their body temperature is inadequate. Failure to meet their needs during this period and adverse environmental conditions can easily cause them to get sick and die. Mortality in chicks is commonly highest in the first seven days. Mortality in the first week, up to 1%, can be considered normal. The causes of deaths exceeding this rate should be investigated and necessary precautions should be taken. Although it is not possible to completely prevent early chick deaths, the number of deaths can be reduced with precautions that can be taken when the causes of death are determined. This is very important in terms of animal health and business profit. Although there are numerous reasons for early chick deaths, the most common causes are genetics, nutrition, diseases and management. Genetic disorders can cause chicks to die while incubating or after hatching. Even if chicks obtained from genetically good flocks are used in production, it will not be possible to achieve the expected productivity if there are problems with care, feeding and management. Good flock management is essential to keep the animals healthy and alive. To reduce early chick deaths, paying attention to the care and nutrition of the parents, storing eggs in suitable environments, purchasing chicks from reliable suppliers if purchased from outside, performing incubation practices per the procedure, taking the necessary precautions against diseases, using healthy and balanced rations and managing the flock well are among the precautions that can be taken.
