Aww, despite parents' best efforts one of the chicks died overnight. Actually there were just two chicks (I'd thought three) and one unhatched egg yesterday. Mother is still brooding the one live chick and the egg. The dead chick is still in nest and it's sad to watch Mom go over to check on it. Surviving chick looks pretty fragile too. Nature sure can be cruel sometimes - looks like it is still cold and windy on that roof.
