I am having a big raccoon problem. I have lost 13 chickens in four days. They have ripped boards off to get in the coop and tore the wire off. I caught one the other night when I went out to check on them. It was in the coop eating the head off of a chicken. My husband shot it. I set a trap tonight and I caught one. They have killed chickens every night for four days. I don't know what to do to keep them away? Any suggestions?
