We put up a piece of birch cut to the width of the house extending just below the entrance hole with 2″ clearance at the bottom and a bit more at the top but the female just hovered around the house. The male was swooping at my husband while he put it up. On a positive note we have 2 eggs this morning. If we don’t get a third tomorrow should we remove the guard? Also, should we plug the other house where the first brood was destroyed or give the wren something to keep busy with (he and the male HOSP were dueling over it yesterday). We’re having a debate about both in the human house. I sometimes long for the days years back when there was an ornamental house in the front and we just stumbled into becoming bluebirders
