I have a chick I hatched that is about three and a half weeks old. He was born with the top half of his beak missing up to his nose. He is eating and drinking just fine. Has loads of energy and feathers are coming in great. He's super sweet and it seems the only issue he has as far as function goes is that since the top part of his beak it missing he can't clean his feet well so I have to go in and clean his feet off for him every other day or so to keep from poo building up on his feet and causing infection. The thing I'm worried about is his size. He is very very tiny. His hatch mates are a little over 4x the size they where when they hatched. He is barely twice the size as when he hatched. He is literally like a third of the size of the rest. Even the midget silkies are bigger than him now. He is not part bantam. Mom is a standard dark Cornish and dad is a HUGE white rock. If all it is, is that he's going to be small I have no problem with that. What I'm worried about is internal defects. Even though he is for all intensive purposes fine, do you think I should be worried he may have a problem like an enlarged heart or something? Any ideas at all?
