I have some baby White Leghorn chicks that i purchased from a hatchery born on May 23. They are growing beautifully, getting big and pretty and a few days ago they start pecking at each other and eating each other's feathers. Now I have a bunch of chicks with bald spots, they killed one and i don't know what to do!!!! They have food, water, a light, good living space, HELP!!!!!!!
