I just got my first duck a little over a month ago as a 4 day old. Petrie, a Black East Indie (probably a drake), is about 5 weeks old and I'm starting to think he has angel wing
He's on 20% grower and has been taken outside many times for bugs. I know that angel wing is caused by too much protein but I had been reading that 20% protein is fine! I'll post pics tomorrow, but is there anything I can do? Is it too late?
