Understanding the Causes of Sour Crop in Chickens

Dr. Emily Carter (Veterinarian, Poultry Health Solutions). Sour crop in chickens is primarily caused by an imbalance in the gut flora, often exacerbated by dietary factors. When chickens consume moldy feed or have access to spoiled food, it can lead to fermentation in the crop, resulting in a sour smell and discomfort.

James Thompson (Poultry Nutritionist, FeedWise Consulting). Inadequate feeding practices can significantly contribute to sour crop. Chickens that are overfed or fed too quickly may not properly digest their food, leading to a buildup of undigested material in the crop. This can create an environment conducive to bacterial growth and fermentation.

Linda Martinez (Poultry Behavior Specialist, Avian Insights). Stress factors, such as overcrowding or sudden environmental changes, can also play a role in the development of sour crop. When chickens are stressed, their digestive systems may not function optimally, leading to issues such as delayed crop emptying and subsequent fermentation.
