I have 2 piggies whose previous owner could not cope with them - one was bought with a fungal skin problem and has started being treated but as the other didn't show any signs, her vet told her not to treat. I have started treating both again and the affected one is improving slowly - my question is, can I put them out on some grass in nice weather? They won't go near my others, but would there be an infection risk to the pen?
