it might be a stuck shed and what i usually do is soak the snake in warm water, about 80-85 degree water for about 10 mins or so and at about 10 mins i gently rub the skin off but not forcefully, it should just slide off. i usually use this method if they already started shedding and didnt finish or missed some spots. but if the snake didnt even start like you said i would just mist the cage with warm water, i would mist the snake itself too. i have my 2 snakes in aquariums and havent had much trouble with sheds if i mist them while in shed and make sure the room they are in stays warm enough as well as checking the interior temps and humidity. i hope this helped, good luck and welcome to the forums!![]()
