As long as I'm here I have a question for you other Cheeseheads. Not long ago I had an egg and a golf ball disappear from the nest box. When I put it in the pest forum everybody insisted it was a snake. I find that doubtful in NE :/Wis in Oct-Nov. What are your thoughts? There is a fence completely surrounding the coop (8x11) which sits on a cement footing with a sand floor. I would easily see if something had dug through. There is an insulated wall right down the middle of the coop so something could have worked their way up into that for a cosy home.
