Its normal the first few times. you nicked him under the skin. no biggy tho :) Good job on your first injection
And yes 1cc is the adult bird dose we go by. (1.5 for full grown jersey giants)
Not a problem. Any questions about the injections just ask. I got my crash course on them early this year. Through my own birds and helping some friends ive gotten pretty good at sticking birds. Remember Tylan goes under the skin not in the muscle.
