I'm new to this site, but I've had my backyard flock of 3 Rhode Island Reds for nearly two years. I have not had any issues with predators until this winter. Been battling mice/moles/rats, but they only seem interested in the chicken feed, not the hens. Then, on Friday morning when I went out to the coop I found one of my girls running free in the snow (which was very odd). I picked her up and when I got to the coop saw that the door had been clawed through. Our coop door is similar to screen door: wood frame and chicken wire with latches. Inside the coop, the heat lamp was shattered, the nesting box was turned upside down...big mess. I found a second hen huddled in the roosting box (which is fully enclosed except the access ramp) and no sign of the third except a pile of feathers. No blood, no body, just gone. We resecured the door with wood planks that day, leaving just a foot way up top (higher than 6 foot) with just the chicken wire...I did that for ventilation as the rest of the coop is covered in tarps for the winter. That night though I closed up the ramp door and locked my two remaining hens in their roosting box. Next morning, whatever it is climbed up the door and shredded the chicken wire again to get into the coop. The feeder was tipped over, but my two girls were safe - although terrified. Any idea what it is that's getting in? I found tracks in the snow that look like racoon, but also other tracks that look like a large dog. I'm sure a dog couldn't get in, but would a fox? I know we have red fox in the woods about a 1/2 mile from our house. What predator would carry a 6 lb. hen away? Help! We've moved the girls into our neighbor's barn until we can fully predator-proof the coop. Suggestions for doing that would be appreciated as well.
