HELP! I have 4 RIR's that will be 6 weeks old on Tuesday. Lemon has been the slowest to develop. She is smaller than the other birds, tends to be on the lazy side. Her head feathers have not filled in as well as the others. She gets to eat with the others, there is no pecking going on except for arguing over a roost when they go to bed. They've been in their coop and run full time for a couple of weeks. A few days ago I noticed she had a few missing feathers on her neck and her neck is much skinnier than anyone else's. They pretty much got the full run of the yard this weekend since we were home and working in the garden. This afternoon I noticed she now has a pink tinge to her face, around her eyes, etc and raised bumps that are also pink behind her ears. Could she have gotten an irritation from one of my herbs? Did she possibly eat something she shouldn't have? No one else has these symptoms. She is acting normally, not weak. Does it look topical, or internal? This was a pic I took the other day which is what everyone else's head and face look like.
