Can someone please help me? Last night something literally ripped the side off the chicken pen and took off the door to the nesting boxes. All four of my chickens were killed, but none were taken or mutilated. The coop is wood and the entire pen (including the coop) is fenced in. The entire thing is covered in chicken wire. The odd thing is that a railroad tie that I had laying across the bottom of the outside of the coop had been moved and the wood and screen of the run was torn off! What can it be? I live at the shore and behind my home is wet lands. Fox? Bear? I am at the point where I am thinking about giving up on raising chickens. This really broke my heart.
