If one is going to put up two Bluebird nestboxes, how far apart should they be so the birds won't fight and decide that neither nest box is useable? Does the concept of "out of sight, out of mind" work (i.e., hang them up on trees on two different sides of a building)? Thanks! Michael Short Pump You are subscribed to VA-Richmond-General.
