I brought my babies home, and I have some questions..
Two days ago, they were eating almost all their food. Last night they barely touched it. Should I leave something in the cage for them to snack on, or leave some new food? I don't want them to dehydrate.
My baby girl sometimes will sit and stare, almost looking frozen in fear, for a very long time. She first did this when a metal piece from a toy was inside the cage, and she'd bounce from side to side and maybe forward, confused. I thought she was just scared of it and I immediately fixed it, then she quit. Is this normal, or should I talk to the vet about this when I take them in for a check up?
Barking. I'm okay with it; I actually think it's cute and it's not that loud, but what can I do to maybe comfort them? I tried a very dim lamp because I don't have a night light at the moment, and I got up and played with them with a feather for half an hour or so. They stopped, but when I left, they started up again. Since we're not bonded I didn't know if there was something else making them do this. But, like I said it doesn't wake me up, but I don't really know what they're barking for other than attention.
On a side note, is it a good thing if they wanted to play even after I brought them home? We had a little scare with my boy because as soon as I opened the bonding pouch to put them in their cage for the first time, he jumped on my hand and planted himself in the hair by my shoulder ( my hair goes down to my hips, and I honestly didn't want him stuck in my hair so I made him go in), but he's always wanting out.
Thankyou.

It's normal for them to go thru phases where they eat more one night and less another. I wouldn't worry unless there are multiple nights in a row that they don't eat. And it's always good to have a gram scale and weigh them once a week to make sure that they're not losing weight. If you want to leave a little food or fresh piece of fruit in the cage during the day in case they get up for a snack, that's fine.

The sitting and staring is most likely just her taking in all the new sounds, smells, and sights in the new place.

Barking is just one of their ways of communicating. It doesn't necessarily mean that something is 'wrong'. As you get to know them better, you'll probably notice that they have different barks and you'll be able to decipher the different ones. Sometimes it's just talking to one another, it could be warning one another of danger, or calling for other gliders. If they were formerly in a place with other gliders, that's probably what it is at this point.

The fact that he wants to play is a good sign. Just make sure when you take him out that you're in a glider safe area so if he gets away from you, it's not traumatic trying to catch him quickly.
