I've just been out to see my piggies and I noticed one, Daisy, seems to have an injury just the the right of her nose. There is no hair over it and I see no sign of blood on it, however, I'm not sure how long it has been there because my sister has been looking after them for the past couple of days.
What could have caused it and what can I do?
