She has a bunch of stuck shed. It's important to get that off ASAP. Put her in a small tub filled with luke-warm water, if it's warm to the touch, it's probably too warm.
Let it sit for 30-60 minutes inside the enclosure and then take a damp towel and rub off the stuck shed.
The food your feeding seems a bit small. Feed something that is the same girth as the thickest point on the snake. :]
If he takes pk, he'll probably also take f/t or live at any time. Get the humidity up for the shed to 60-70%.
Make sure to have a temperature gradient, with the cool side (1 hide, water bowl) between 80-85F (this should be the same as the air temp in the tank) and the warm side (one hide) 90-95F. You can achieve this with a proper UTH with a Thermostat, and if you need a better air/ambient temp you can use a red lamp to push that up.
Also, a papertowel roll will not suit as a hide. It should be something tight and round with one opening (no log hides!) and identical is a good idea too.
Another good idea to relieve some stress, is to cover 3 sides of the enclosure with black construction paper or something dark to make them feel safe and enclosed.
Good luck! And welcome!![]()
