I left this morning on vacation. My little flock of 14 chickens was safe and sound when I checked on them last night at midnight. My BIL went to take care of them late morning and found complete carnage. 1 left out of 14. Since I'm out of town, the whole report of what happened is second hand. I wish I had pictures. My birds were in a tractor covered in hardware cloth, with an apron 2 feet on each side on the ground. The shaded part was sheets of roofing heavy duty plastic stuff. The animal tore through the roofing material--the one place I never would have thought possible! There was one chicken dismembered, 3 missing, and the rest just...dead. Little bits of yellowy fur were around the entrance point. Would a dog have done this? Fox? I'm heartsick about this. 1 chicken left.
