Scab on lower back?

[Samsters94]

I am very concerned.... I went to go brush my chins today and my buddy Godric has a scab on his back... It is about the size of my thumb. My work schedule was busy this week and my friend is dying of cancer so i haven't held my chins in about three days. i check on them though but today i took them out and Godric has this scab....My other chin is okay though. Nothing on him. Should I be worried they are fighting and Godric is the one getting hurt? I never see them fight though. Just mount each other sometimes. Here are some pictures... Please someone help.

It looks like it could be an injury from the other chin. I would seperate them.

I'm not sure about the scab, but I would separate to be on the safe side. You don't need to brush your chins at all either. I think some people comb them occasionally, but it's not really necessary at all.

well I know they can't vomit and my chins clean themselves a lot :/ but yeah I will be separating them as soon as possible....
