I now only have 2 hens left. this cat has taken 3 of my hens over the past month or two. The most recent being yesterday. He is super friendly, I know because I was hanging with him before he started taking them. The first one him and this other cat took. but the next two I think he took by himself. I have never seen any of these cats before and my rooster is not chasing them off. What can I do to keep him away? There is no body left over that I can find just feathers in one spot then they are gone..
