Pigeon milk is a nutrient-rich substance produced by parent pigeons to feed their young. Unlike mammalian milk, it is not a liquid but a semi-solid secretion that comes from the lining of the crop, a part of the bird's digestive system. This unique food source is high in protein and fat, providing essential nutrients for the growing chicks. Both male and female pigeons produce this milk, which they regurgitate to feed their hatchlings. The production of pigeon milk typically occurs during the breeding season, and it plays a crucial role in the early development of the chicks, helping them grow strong and healthy.
