Question Should I remove 5 eggs that were laid 3 or 4 weeks ago. The mother and mate still return to the nest but I fear the eggs were not fertile?
Answer When the eggs are laid, the parents may or may not start to incubate them, for some reason. The eggs will stay fertile and good and when incubation begins all will be fine. Three or four weeks is unusual but that could be the case and the eggs may still be good. The eggs of course may be infertile but you just don't know. Bluebirds are promiscuous so the eggs might be from 3 or 4 fathers, so some might be fertile and some not. So......... my intuition is always to let nature take its course. If the parents finally give up and disappear for a week, then you know it it safe to remove the eggs. Otherwise, let things be.

Thank you for your quick response I will keep my hopes up that all the eggs will hatch. As i said both birds are at the nest daily..
