I woke up this morning to a bloodbath in the chicken run. I already lost 11 of my 14 hens to fox attacks this spring while free ranging so I have been keeping the remaining 3 locked up in their run. Last night/this morning something pried back the hardware cloth under the run door, dug its way in, and killed 2 chickens. One carcass was left headless in the run and the other was completely gone except for feathers and bits of bone. Of course my first thought was fox, but could a fox fit into that little opening (about 3x6")? And would it leave anything behind? Raccoon?
