I have 4 bbb hen-turkeys that are almost a year old. They were peacefully coexisting until this morning. They have a shelter that they share every night, and they free range during the day. This morning 3 of them started fighting each other. Trying to pull them apart and separate them temporarily simply didn't. Finally one of them lost all the fights and had to hide, and now the remaining 3 turkeys turned agains her. They are ganging up on her and keep viciously tugging at her skin like turkeys do, her face is all scratched up. The only thing I can think of is that we've had a couple of warm spring-like days and this weather might be waking up some of their sexual behavior instincts. One of them started strutting like a tom and making those spitting sounds. Today 2 of them were doing it. My head is spinning lol. My nice peaceful turkeys turned into monsters in just one day. I am new to turkeys and I am having hard time understanding their behavior. Can someone explain why they are doing this and if there is a way I could stop them from fighting? They have been exhibiting sexual behavior since fall - squatting and laying eggs. We used to have a tom, but his legs gave out and we had to slaughter him, and that was about a month ago. I've seen my hens fighting a few times, but those fights never lasted long and they always went back to normal soon after. I've never seen them as aggressive as they are now or the fights going on for so long, or them ganging up against one.
