Darla has black on one nostril and I have no idea what it could be. I noticed it when I was in the shower with her and buttercup. I thought maybe a bruise but I don't recall her flying into anything. I'll try to get a photo but anyone got any ideas what it could be? You can't see anythung black actually in the nose as far as I can tell, it's more like the skin around the nostril that's tinged black. She's a wf cinnamon pearl pied so it's definitely not just the normal change in colour you'd expect from some mutations.
