If you can get the toes flattened out, sandwiched between 2 layers of bandaid to make little orthopedic shoes for him, they may be able to be corrected. It sometimes works, and other times does not. You will have to change the bandaid splints often as the feet grow. Mineral or cooking oil will allow you to remove the bandaids without injuring the chick. Do a thread search for curled toes, orthopedics, or splints for curled toes and you might find some photos.
