How long have you had her?
bonding takes a lot of time, and crabbing is normal, especially in the first few weeks and months! The more patience you have, the bigger the rewards in the end! Just take it at her pace.
If it was really traumatic for her to be taken out in the pouch, back up a couple steps and just sit quietly by her cage to allow her to get used to you that way, in a less threatening situation. See if she'll approach you through the bars of the cage to take a mealworm or a licky treat like yogurt off your finger. Don't be discouraged if she won't at first, though. Time and patience are the most important things to give her.
Then after a few days of being near her cage as much as possible, put the
bonding pouch in her cage as her only choice to snuggle down into when she's ready to go to sleep for the day. Then when she's sound asleep inside, gently remove it and zip or close it up and start carrying her with you. That way you don't have to upset her by transferring her from one pouch to another and she gets used to your scent while she's asleep. She'll still probably crab, but just keep it up, and she will eventually get more comfortable and stop all the noise!
Giving her the pieces of fleece that you've worn on you is a great idea too. You could also leave a T-shirt you've worn or slept in draped over her cage.
If you haven't already, check out the
bonding links at the top of the page under GC
links. Just remember, when you first bring home a new glider, they are almost always afraid and crabbing and striking is just what they do. It may seem like they'll never like you, but if you stay consistant and patient, it will pay off many times over in the end.
I just got my second glider last weekend, and we are going through the whole crabbing thing too. Feel free to PM me if you need anything.
