So this morning I went out to check on the chickens, and they are all dead!!!! Two chicks are missing and one was half drug through the wire at the back of the cage. All the adults have bite marks on their heads but no where else! All the eggs were eaten and some shells remained. Feathers are everywhere, I looked and could not find any holes in but it did snow a tonne. The only thing I found is by the chick that was drug through the cage is long poop littered through out the snow. What kind of animal does this?? Also the pen has wire all the way to the ground and out and is covered by logs and rocks.
