I had a similar experience. I had a chick who would not eat, anything. Till one day she decided to eat, then she grew rapidly. At first she grew feathers then once she got her wings she stopped. When she grew rapidly she only got to half the size she was supposed to be but before that, she was only 1/6 of the size. I fed her plain yogurt, egg, and anything I could get her to eat, mixed with her food, but she just wouldn't eat. One day she decied she was going to. She grew to be five months old, but then injured her hip and leg and had to be put down, as recommended by the vet. I missh her so much, and hope your little guy has a happier ending. Here she is at 2-3 months old.
