Ok, I'll just start out by saying that me and my renter free range (our renter used too) our chickens. I have a nice hen house that I can walk into. About a two months ago our renters called and said they had a chicken disappear with just a pile of feathers. A couple nights went buy and another one disappeared but this time there were feathers and a body with no head. The next night it came back and got the body. This continued a few weeks until they only had one chicken left so they gave it to us. I shut our hens door at night so nothing can get them and we had no problems for a long time. But one day in the middle of the day one disappeared and we found a body with a bite to the neck and back and feathers here and there. A couple days went buy and another one gone with feathers and a mangled body with bites in the same area. Now it comes about every 5-7 days. This last time it got three of my chickens in one day and injured one! I found 1 body with bites on the neck and back. One pile of feathers and no sign of one. I put all the chickens up and put out two live traps but have not gotten any thing. Does anyone know what I'm dealing with and what I can do!? Any help would be greatly appreciated.
