Finally got a good look at the nestbox and was able to spend some time watching here this afternoon, and there is only one chick. No chance now, I would think, for any of the other eggs to hatch. The parents are both very devoted to Genesee Junior, both coming into the nest box and fussing about, while he/she was making it very clear that it was starving to death and would have a temper tantrum if things did not start to look up.
