The first night 3 of our female quails were plucked on the side of their body, feathers were torn out and lots of blood. A few days later the rest of our flock-4 more, (1-male, 3-females) were found dead with no heads. We aren't sure what killed them, either a raccoon or rat. Yet there was no damage to our hutch if it was a raccoon. Now I have been reading up on rats and they could have fit through the chicken wire we had. So I think it might be rats. Though a day later my husband found a pigeon in our front yard headless as well and the rest of the body was intact. Would a rat just eat the head and nothing else? Thoughts?
