Well I don’t raise this one outside anymore it used to be raised outside with its friends but they all got attacked and this one was the lucky one, but they use to have dirt now they have just home floors I clean it’s sleeping cage everyday to prevent anything
It could be the start of footpad dermatitis. If you havnt done so, put a roost in the cage for her to perch so she doesnt have to sit or sleep on the tray. Keep litter dry at all times.
