There are several factors that can cause stunted growth in two-week-old chicks, including:
1. Poor Nutrition - Chickens require a well-balanced diet to grow and develop properly. Feeding your chicks with a nutritionally deficient diet may cause stunted growth.
2. Disease - Various diseases like Coccidiosis, Marek's disease, or Fowl Pox can affect the growth and development of young chicks.
3. Stress - Stress can cause stunted growth in chicks. Stressors like overcrowding, sudden temperature changes, excessive noise, or poor living conditions can all affect the growth rate of young chicks.
4. Genetics - Stunted growth may also be genetic, with certain breeds being more prone to growth problems than others.
To prevent stunted growth, it's essential to provide your chicks with a balanced diet, clean and comfortable living conditions, limited exposure to stress, and proper healthcare. Consulting with a veterinarian can also help you identify the underlying cause and determine the appropriate course of treatment.
