Hi Everyone, My 4 male calls are about 1 year old. They have always been together and live in a large 8x14ft pen. Recently, the smaller ones have been pecking at the largest ones neck. This has resulted in his feathers falling out (or being pecked out) on the back of his neck. It actually looks like someone buzzed his neck with a razor. Should we be concerned? Is this a dominance thing? Should I take him to the vet or is there anything I can do? Hope you can help! Thanks!
