I have a 13 week old Barred Rock roo. I noticed he had a red spot on his wing. I thought at first he hurt himself. I was able to catch him today and the red spot was actually one single redish feather. He is from hachery stock, I got him at the feed store. I'm taking a wild guess that this is not normal and mostly likely it is because he is from a hatchery. Is there any other reasons for the one single red feather? Just wondering. Thanks.
