My two golden comets are fighting each other at sight. I have 6 hens and the two that are fighting are going for the comb, earlobes, waddles, etc. I don't know what to do or why they're fighting they've been together since they were chicks and never had a problem before. They have plenty of water, food, and space so I don't know whats going on. It all happened so randomly and I really need help.
