Just a quick FYI on the little one that hatched out early and is not growing. It may grow much slower than its clutchmate due to the early hatching. I have had a few cresteds that hatched early or were smaller than normal on hatching (last clutches of the season from a female are sometimes a bit smaller than normal) that seemed to grow very slowly at first. Eventually they caught up and were just fine, but it did take some time.
