Last year I lost roughly half my flock to what I'm sure was a coon. We set traps and caught a she coon but that was it. The killing stopped and then a couple days later started again. We lost 2-3 chickens a night. We put up an electric fence and for a few months nothing happened. All our chickens were living happy peaceful lives. Fast forward to last week. We find that we had lost 3 chickens. 2 of them looked like they hadn't been touched and 1 was completely devoured. The next day another one dead. This time it was my black copper maran. His head was completely gone. To make a longer story a little shorter our flock was reduced from 10 to 2 in a week. We got to the point where we were taking the chickens after they had gone to roost and putting them in a small cage next to the front door of the house. That's worked well so far but last night when I went to get them Neither were on the roost. One I found hiding under the coop and the other no where to be seen. I finally found it's headless body laying close to the coop. This was about 7:00 PM when I found her. The same time I've been going out every night to get them. So finally after a week of losing chickens I'm down to a single leghorn hen who looks so pitiful and I feel so sorry for. Over the week we added new electrified wire to the fence, replaced the module for it and dropped a couple cinder blocks over 2 places that looked like something tried to dig in. My question for you good people is, what is killing my birds and how do I kill it back? I've set traps and they don't work. I've sat out there hoping to spotlight the little blighter. I just don't know what to do. I want to remedy this situation before spring so I can try and rebuild my flock.
