I am not sure I can see what you mean about skin covering the nostrils. Both look open to me in the photo. However, the tortoise does appear to be very dry, so probably keeping it in a more moist environment and soaking it daily would be a big plus. It also might loosen up the skin you say is covering the nostrils and help it to slough off.This is not my tortoise but I’m wondering what your input is on this redfoot’s skin. It appears overgrown and is covering his nostrils almost to closure. Is this from dryness or dehydration?
one of the nostrils are ALMOST blocked by the "skin" (i wouldnt call it skin tbh, maybe it's just naturally small?? or shedding skin??)yes the picture quality isn’t great, but if you zoom in, it’s like a layer of skin covering the face and almost blocking the nostrils.
I would suggest wetting it down thoroughly with warm water and trying to gently peel off the entire layer of skin (or whatever it is if not skin). Then see if it comes back or not when keeping the tortoise under more moist/wet conditions.yes the picture quality isn’t great, but if you zoom in, it’s like a layer of skin covering the face and almost blocking the nostrils.
