Very alarmed last night to see one of my ewes with blood all round her muzzle. Cleaned her up and it looks like she's managed to stab or scratch herself (probably a run-in with a gorse bush) on the flat bit between her nostril and her top lip. This morning she had a clean face and I thought we were all good, but on closer inspection, it's still bleeding very slightly - I think she's knocking the scab off as she grazes.
There's nothing still stuck in there, that I can see, no lumps or bumps, just this tiny area that's very slowly oozing blood. She's her normal self otherwise, grazing happily and mugging me for sheep nuts. I've cleaned it up again - anything I can do to help it heal or just keep a close eye on her and let nature do its job?
