Over the last week I have lost twenty of my chickens. These chickens were the first batch I raised and every time one dies it makes me cry. I have sealed off everything I can think of in the coop and I make sure to lock them in at night but something is still getting them. It started off last saturday with one or two dying each night but last night whatever it was went on a killing spree and got over ten chickens. I almost always find them with their head and neck missing. The first chicken to die actually had its head pulled out of a hole and it was a silkie who was only about three months old. After that I went on a mission to seal any cracks or holes but still they continued to die. They are always fine when I go to close them in the coop but by morning I find carnage. What could be killing them? I have to go with my family out of town soon and I want to stop whatever it is. Sometimes when more than one is killed it doesn't take all of the heads of the chickens it kills.We have live traps and so far all we have caught is a skunk. Even after it was gone the killings continued so I know that wasn't it. Last night my favorite rooster was one of the ones killed and I have had it. I want to find whatever this is and end it.
