I guess I will just leave the house up then and make sure it stays “clean.” It would be nice if the babies I saw were the ones that I bought all of those worms for :-) I live in a pretty rural area where the houses all sit on about 2 acres each. Several of my neighbors also have bluebird houses in the back yards, and I’ve seen their “couples” when I walk my dogs. I guess that some of my babies could have ventured that way.
