We have a window in the back of our coop. I open it every morning and close it at night. There is a screen in it. I don't like going into the poopy coop unless i really have to. Dh covered it with chicken wire. It's a ways off the ground. Would it be ok to leave it open all night with the chicken wire on it.....or could a critter climb the wall, take off the chicken wire and push through the screen??? Sorry for the silly question. Dh thinks it should be fine but i worry that predators are everywhere and will do anything to get my babies.
