A couple of scabs on back?

[Rebecca01]

Hi

When grooming my four pigs today I noticed that one of them had three little scabs under the fur on her back ( two together and one a bit higher up her back)
The skin around them doesn’t seem to be too irritated although my partner did that he has noticed her turning around to groom that part more so maybe it is a bit itchy? I haven’t seen her itch that much but occasionally
To me I don’t think it looked like fungal, and i haven’t noticed anything yet on any of the other three, are these cuts from scratching herself?
I am happy to get some xeno to help in case of mites and I’m going to avoid brushing near that skin at the moment but just wanted some ideas on what it could be

It would be best to have a vet check her - please don’t treat her with anything unless a vet diagnoses her. (Xeno is actually in short supply so you are unlikely to get it in any event).

Should I wait a couple days to see if they go first in case maybe she’s just scratched herself, or tk see if it gets worse?
