They are incredible aren't they? I have two that do the same thing. One in particular, Cinnamon, took to feeding the two we had started handfeeding as well as three other of his chicks. He'll feed anything that chirps at him.I need about 3 other father birds just like him; he's feeding six chicks, and doing it because HE insisted that we let him, after he had camped out on the brooder for over a week.
