Pigeon milk is a nutrient-rich substance produced by parent pigeons to feed their young. Unlike mammal milk, it is not a liquid but a semi-solid secretion that comes from the lining of the parents' crop, a part of their digestive system. This unique food source is packed with proteins, fats, and antibodies, helping the chicks grow strong and healthy. Both male and female pigeons produce this milk, which they regurgitate to feed their chicks during the first few weeks of life. This process ensures that the young receive essential nutrients and hydration, as they are unable to eat solid food until they are older.
