H Cheri,
I’m sorry you lost the chick. But this is not uncommon. Sometimes a chick just doesn’t survive. There may have been something wrong with it, maybe the parents didn’t feed it enough or with one chick, they might have over fed it. They fall out of the nest all the time and the parents go down and care for them, so it wasn’t that. And it wouldn’t have known what to do with food and water if the feathers hadn’t come in yet. Take the nest down and rest the parents for a few months before letting them try again. You should do this after every clutch.
Thank you for asking Lafeber,
Brenda
