Hi!
Congrats on your new sugar gliders.
I like the idea of turn the lights on and put yummy treats in the pouch, then offer the pouch to them.
What time are you doing the tent time? If you do it in the early morning before they go to sleep they may want to go in the pouch more.
To be honest, I still have a couple who don't like to ride the pouch back to the tent. So I literally wait until they're on me, then unzip the tent and head straight to the cage. Clare Bear is a spaz and will leap to the cage as soon as I'm in range so I have to make sure the door is open and get there quick! Fionn will literally climb out of the pouch to ride my shoulder to the cage, then runs down my arm and jumps from my hand to the cage the moment I get there. So, that's a possibility. Just be careful no other pets are around in case one gets all kinds of curious to explore suddenly.
And just by the way, mine never sit in my hand. When they're awake, they're much too busy playing. At best they use me as a jungle gym lol. I also never trained them to be in my pockets. Turns out girl clothes have really small pockets....plus, it's just easier to let them snuggle together in their cages all day.
