A few days ago I went to check on my 14 girls locked up in the coop. Only to find all but one dead. I was so traumatized since these chickens are my pets and I was so attached to them. After 8 months of raising them, they had JUST started laying eggs. I've lost a couple to sickness, but nothing like this. There was blood and feathers everywhere. Whatever is was was still in there because I saw it pulling one of the bodies under something. When I got over there it had disappeared. Later my husband and I checked everywhere and couldn't find any digging holes or anything. We have a buried perimeter around the coop, hardwired cloth over the vents and made it super secure. It's a total mystery. After days of research, the only thing I can come up with is possibly a mink or weasle climbed the coop door and got through the 1 inch gap at the top. To make a long story short, I don't know what to do with my one girl now. Building a small coop in our basement is probably my option until maybe I can start over the flock next year. It's too cold to put her in a coop by herself over winter. I'm very upset and wondering why I didn't know about mink before. I always worried about fox. Anyone else had this issue?
