So I'm not sure if there's a need to worry or not. My chicks are going on 5 weeks and I noticed that one BCM is considerably smaller than everyone else AND it has a bald patch on the middle of his back and the top of its wings. Also on the bald patches are a couple scabs. I'm assuming he's just getting picked on, but I didn't observe any of it for the hour I spent watching them today. I checked it and the others for parasites and didn't see any. It's acting completely normal, eating, drinking, pooping. That's him/her on the right next to the biggest chick. What do you all think? Are there any weird skin/feather conditions that might apply here? Thanks!
