How old is she? Have you soaked her in some warm water. A lot of times when a snake goes into shed you can smell ammonia, so that may be the smell you were getting. She may be dehydrated. Do you have a knowledgeable vet in your area?

You mentioned you moved? I would double check temps and humidity. Don't know how you're set up or moved from where to where but looks like snake is trying to tell you her enviroment has changed and it's not quite right? May have to readjust things for new place. Up here in the NW having to adjust as winter showed up! Hopefully it's that simple!

seriously, I'm with Lash.  in Seattle in the winter, it's rain-rain-rain...not intuitive, but once the weather changes I have to go through a big increase in humidity and misting every year. I think it's because of how much it dries the air inside, to run the heat.

good luck with her, and hopefully she'll straighten out and be fine for the next shed.

Yeah, I was wondering mostly if the move impacted her.  We checked temps on all our snakes and everyone's measure the propper ambient temp for their needs.  But about a week before we moved they all got put into a rack system, which so far has helped everyone.  But I could see where the sudden change in weather would put a beating on them.  It's just her that I'm seeing the most, if any issues with at all.  I totally left my camera at work so I'll have to wait until tomorrow to get some decent pics.  I wont even attempt with my cell phone.  I would have to scratch my head if she was dehydrated because I upped her humidity once I noticed she was going into shed.  But she does look I guess you could say "wrinkly" as if she were skinny, but she's been eatting normal.  I'll have to pullher out again soon and see how her personality is and if she seems anymore lethargic.  As for a knowledgable vet, yes I have one.  We live over an hour away right now but if things increase I'l def. make an apointment for her.  As for age, she's an '09 I'm not sure what month she was born though.

Is she still "wrinkly" where the old skin has been shed off?  Sometimes right before my snakes shed, they get a little "wrinkly" looking from the old skin being tight (I'm guessing that's the cause, may also be indicative of sub-optimal humidity + shedding in both our cases).

She may have neglected to shed that old skin. I'd set up a soak box in her enclosure and soak her in a few inches of water for several hours to see if it helps.

+1 gfx and Lash, soak a good long soak and then check and re-check temps.

It's not uncommon to see bad sheds once the winter months hit.  I have a carpet going through a not so good shed right now.

I agree with the others about soaking.  But I don't think it's cause for panic by any means.  Not unusual.

What are your temps for her?
I agree with Lash and GFX, make a humidity box or a box of warm water and soak her for a couple of hours. Is she still eating?
I'd focus on making sure those temps were right and getting that stuck shed off her. Once thats good, dont handle her for a few days and offer her a nice warm meal. As long as her temps are good, and she's eating and gets all that shed off her, I think you're good. As long as any other symptoms don't pop up...
Good luck! And keep us informed.
