So I came home from work and it looks like there are some sores on my runners. They all have pink (bald) spots on their wings (normal?), and one seems to have a sore on her face. If this is just roughhousing, should I separate them? Is there some sort of deficiency? I'm concerned but everyone seems healthy. Any thoughts? see the pink spots on the wings? This one is hard to see as i had to zoom way in to not spook them. They are huddled because I was freaking them out, not because they were cold.
