I'm at a loss at to what is happening. We haven't had an egg in 4 days and every morning there are a lot of feathers on the bottom of the chicken coop. It sounds like something is getting into the coop every night, but there is no sign of entry or egg remnants. The coop has chicken wire on the floor, a locked door and a locked window that we close at night. Any ideas what could get into the coop and not leave any traces? It must be something that can fit through a very small hole. Need help desperately!!
