That's pretty common. It's important not to pull on it because it may still be attached along the membrane in his nose. When the shed is ready to go you'll see a plug start to appear from the nostril and may look loose while he breathes. You can gently rub it with a q-tip or similar to help bring it at that point because it is likely detached. Until then, he will be a bit uncomfortable and might breathe from his mouth more than usual. It's part of their face shed cycle though.
Omg I feel so bad for him... it looked like he already had some skin that resembled a plug come from his nose and that little thin layer of skin is what was left. I just gave him a warm bath, as I noticed some more shed around his mouth and eyes.. Poor little thing! I hope it works itself out soon! Thank you again for your advice!
