I'm having a heck of a time keeping mice out of feed bins. I have blastic trash cans and metal trash cans but they don't hold as much feed as I'd like to have on hand. I was think about using a large metal trough and making a lid to put on top. Pictures would be appreciated :)
If you can get your hands on an old deep freezer, the chest kind, that doesn't work anymore, this is what my parents have had for years and never had issues with mice (unless the door gets left open by accident).
