What's causing incomplete sheds?

You are not doing anything wrong.

I work at a zoo, and I see this all to often.

You sill wan't to keep the humidity up, but give them a water bowl that is big enough for them to curl up in. This will help keep the humidity up, and help keep the skin moist. Also try keeping the cage slightly warmer.

Put a rough log or rock in the cage, just something to rub up against.

If you are still having trouble, you need to soak them yourself. At work, we use a big plastic barrel to soak the snake in. You can just use a small plastic Critter Keeper. Make sure the tub has plenty of air holes because you will soak the snake until all or most of the old skin is off.

Good Luck

You don't need heat on a corn snake for one, unless you live in the arctic, Alaska, or any other country or state that is below freezing. It could be from a lack of nutrients. I have two rat snakes, which are a close relative of the corn and king snakes. I have had that happen one time, that was when I first got my snakes five years ago. And I used to work with a breeder, who has been breeding reptiles and amphibians for over thirty years. I have seen it done once, and I have done it once, but you could put your snakes in warm water, and let them soak for a few minutes and then gently take a towel and wipe the skin off. DO NOT PULL IT OFF. You can also call a vet and ask them for their advice.

Stress could be your answer. If your humidty is fine and heat is fine its probably a little stressed what you can do is put some wet moss inside its hide. Or give it a luke warm bath for 5 minutes then with a towel gently pass the snake through it and should take off most peices dont pull the sheds off just pass your finger over it

It doesn't seem like anything is wrong, maybe turn up the heat 1 degree and put some coarse rocks in, two rocks side by side with just a little more room between them so she/he can move between them. Also clean your tank and lay down some clean Reptile Bark form Exo-Terra (one of the best brand names). And if you are really looking for more moist get a water valcano that shoots up spay into the tank when you wish. But other then that all it can think of is taking them out when they shed and help them a little by putting them in a large tub with lots of coarse things so they will easily loose that skin that you are talking about.

Hope this helps!

your doing nothing wrong. sometimes they just have a bad shed. it could be from stress.... but just soak them in a bath of warm water for about 15 min, and then run them through a towel so the skin comes off. I had that problem to, and this method worked like a charm!

not having the correct humidity in the tank. Also, their skin may not be moisturized enough, like they didn't soak in the water long enough to loosen the skin.
