two dead chicks

The strong winds we've had recently appear to have blown one egg out of each of the Yellow-Crowned Night Heron nests in our front yard. It's hard to tell whether the chicks had hatched already; the egg shells were on the ground as well as the chicks. One was dead, the other soon to be so. Its futile struggles were disturbingly similar to the weak, random movements of a young infant. I sure hope there are more in the nest. Wikipedia claims there are usually 3-5 eggs.
