It seems maybe she isn't happy with all the touching, so I would first stop
that. if you need to pick her up, use a large piece of fleece as protection
for you hand so she can't bite you. Seems like biting is becoming an acceptable
habit for her. Don't let her bite you anymore.
second, go to a website that lists different bonding tricks and start at the
Your hand has become a source of danger and stress to her, in need of
protecting herself against it. So.. I would start by just getting her to
eat a few treats from my fingers/hand and having her not bite me. After a few weeks, (I would stop the bonding pouch for now, its not helping) I would move to
the next step, keep one hand LOW and SLOW, then put the treat out so she has to step
on your hand with one or two front feet to get to the treat. MEALWORMS are great, dried ones kaytee in bird food section of store, live mealworms can cause a newer glider to get over excited and bite your finger while trying to get to the worm.
so... over time try to get the glider to get on your hand/arm to get the treat.
then finally sometime in an unknown amount of time, you will get your glider to sit on your hand/ arm to eat the treat. Your arm/hand is a safe place, a place that doesn't need to be bitten.
One of our gliders, scarface, still runs away, but if I have to pick her up she will give me a baby nip, but not a big bite. its like she isn't happy and wants to
let me know, but also seems to understand she doesn't need to get me a hard bite cause my hand isn't that big of a danger. same as in sleeping pouch, she will give me little nips then move around to try to hide behind the other gliders.
