I had a possum get in my house and scare my girls too- it ate an egg and their food...they're all okay (they are a nervous bunch in the first place), but now they will not go in their coop at night, even though the possum is gone. What can I do? I have cleaned the coop thoroughly and replaced all their bedding in hopes of getting out the smell of possum, but they WILL NOT go in there at night. They all roost on a chair by my back door and behind my trashcans. I have to dig them out every night and shut them in. This routine is getting old. Help!
