To add to Zin's advice and in case the stuck shed is very stubborn, get a wet pillow case (or other cotton bag or cloth) and wet it, not dripping wet though. Put Axel in there and let him move around for a bit. Maybe hold Axel in the bag, apply some gentle pressure as he moves around to help catch the wet shed.
Try for about 30 minutes and see if it helps pull off the stubborn shed. You could go more or less on the time, just not sure how much it'll bother Axel.
Good luck! Stuck sheds suck!
