I have a home-made coop, that sort of looks like a shed. It's raised on cinder blocks, so not a whole lotta room for the girls to go under. This year, I noticed a couple of holes on the two sides of the coop, where the run is not attached - so the outer sides of the coop. I believe it's a groundhog, since I've seen one in that part of the yard, but have not confirmed. What risks does the little varmint pose to my flock? It's not touching the food and I really don't want to have to kill it.
