Some people have been concerned about the 3rd and most recently hatched chick. Yesterday during the feedings (at least during the ones that were not blocked by Astrid standing in front of the camera!) it appeared as though that chick was not being fed. It’s only natural for raptor parents to favor the older and stronger hatchlings especially when food supplies are limited. That is how they insure that their nest will at least produce some young in a given season. Since food procurement is not usually a problem for urban Peregrines, it’s likely that there will be enough for chick # 3 and # 4, assuming that final egg does hatch.
