Dang those things are persistent! They already gnawed five holes on the bottom of my coop which it is setting on patio blocks with wooden floor laid down rubber mats on top. We have tried death baits and got three of them, but the rest of them just by pass those baits and getting into the coop. They dont bother the eggs or the birds. Sometimes they would drag away a chick or two and the feeder are hung up on the wall about a foot. Anything I can keep them accessing into the coop via thru floor? I thought about replacing the floor again and line it with hardware wire and wrap it all around the bottom and sides and a little extra lip on the top. My shed is a Royal Outdoor shed, the vinyl ones.
