chickadee nest in my bluebird box
Ihave had avery successful bluebird box in my yard since I moved in seven years ago. Over the last couple of weeks chickadees have seen fit to move in and build a nest. When I checked the box yesterday, the nest looked complete, but there were still no eggs. My question is: Should I let the chickadees continue on with the risk of being accosted by the bluebirds, or should I destroy the nest?
