What is a Chicken? A Look at the Bird We Love to Eat

The chicken is believed to have descended from the wild Indian and south-east Asian Red Junglefowl which is biologically classified as the same species. Chickens (Gallus domesticus) are domestic birds that cannot fly. Many immature males (cockerels) are castrated (usually chemically, with hormones that cause atrophying of the testicles) to become meat birds (capons). Farmers have developed numerous breeds and varieties to fulfill commercial requirements. At about six months, males produce viable sperm, and females produce viable eggs. The time between ovulation and egg-laying is approximately 23–26 hours.
