We recently found out that some bird made a nest right under our porch, and laid 3 to 4 eggs in it (you can see them through the spaces between the planks). But the problem is that very often when somebody is leaving or entering the house the mother bird flies away and comes back in about 5 to 7 minutes. I started worrying if any babies are going to hatch from these eggs at all? On the other hand we cannot stop using the porch and leave and enter the house through the window:-( The bird is some wild forest one with reddish chest of a medium size (slightly bigger than a sparrow). Thank you!
