@kfelton0002 a question about the injections - they're all really skinny at the moment. No real breast muscle to speak of. Even their crops aren't especially full. Is there another muscly part it can go into?
Injections should always be given in the breast muscle or subcutaneously because birds have renal shunts. You can give Tylan orally, but I'm not sure if it's ever given subcutaneously.
