What is up with the nest box stealing? My NRs are insisting on moving out, moving up, moving into things that are not theirs, taking over the others nest boxes and basically not liking their home unless they are stealing it from someone else. First I thought it was because they were dirty, then I thought it was because I cleaned it, then I thought it was a particular blanket, location, a cache of nuts, height...well you get the point. No matter what I've thought the little stinkers just thumb their noses at me and one day its fine the next day they want to move. Any insights on this behavior? I've been intervening and putting everyone back where they belong. Should I just let them figure it out? Will they hurt each other fighting over houses? Any thoughts or advise would be appreciated.
