Something dug in and got our flock, all fifteen. Trying to figure out what it is that got them. It dug in around an unburied fence skirt, and under a bottom rail. It didn't dig out much space. My first thought was racoons, but my bil's family thinks that it might be a mink/ferret/etc. Any thoughts on predator in SE Michigan. It left some dead chicken carcasses if that makes a difference.
