sounds like she was dehydrated. Check the water bottle make sure it's working properly and has water in it.
What diet are you feeding?
When gliders are dehydrated they can't regulate their body temp properly and feel cold to the touch. If gliders are severely dehydrated they will have seizures.
Orange juice is very high in vit c and not our first choice for rehydrating a glider. The vit c makes the internal organs utilize Iron at a faster rate, Iron is already hard on the internal organs so it's not something we like to optimize.
In the future if your glider becomes dehydrated keep the glider wrapped up and warm, use orange gaterade mixed 50 50 with water to rehydrate. Hold the glider vertical and offer a few drops at a time on the side of the mouth to avoid the glider aspirating until the glider starts to drink on its own.
If your not sure if he or she is dehydrated pinch the skin on the middle of her back thumb on one side of her spine finger on the other side of her spine and pinch. If the skin stays up like a tent the glider is dehydrated, if it snaps right back to normal it isn't dehydrated.
