Y'all were right, something was probably wrong with the chick.
A full supplemental handfeeding quickly in the nest for the remaining 4, each morning and evening the last 7 days (they are 11 days old now), proved to be successful.
I opened up the nestbox for their evening meal after days of lazy half-feeding by mom and dad and WHOE!!
This is what I find. And , oh boy, are they now noisy!! They are not model parents, but I think we are over "the hump" so-to-speak. I am elated this evening! I get to sleep IN tomorrow ! WOOO!
