Hello, I recently joined the forum. I have been raising chickens in Michigan for about 6 years. When we first built our coop and run, we tried to secure it as much as possible, and we have never had a problem with predators in the coop before. We live on 10 acres in the woods, so predators are plentiful. The other day, I went out to the yard and found 5 of my 6 birds dead. There was no blood and it almost looked as if something killed them, but did not eat them. We found a small hold in the chicken wire of the coop. Any ideas of what this was that got in? Thanks!!
