My (estimated) 7-8 week old pigeon with severely splayed legs (awaiting surgery next week) has not grown full feathers and still has bald spots on the middle of his upper back. Is this normal? He seems developmentally delayed -perhaps due to the trauma in his fir t two weeks when he was found - and still does not eat fully on his own. He eats from my hands. Could the late feather growth also be due to delayed growth? Thank you.
