Confirmed!! Those dirty rotten little mice. I tore my coop apart today for the spring hose out sanitizing... It was so gross and filthy. I found mouse nests that had hay and a butt load of chopped up feathers.. Ok, I was trying to be humane, but screw it. I'm going to start using glue traps from now on. Everything else is a hassle and they wise up to them. Well, its crack down time! I'm sick of them!!~!
