I think you just need to put in the work with the unbonded gliders. its going
to take time and work, but that is half the fun of having them. treats and tent
time and petting.
you can put them together if you want, but i dont think it will help to much.
I have 6 in our colony and one female just doesn't like humans much, I can feed her
treats, sometimes she sits on shoulder to eat a treat, I can give her a little pet
and she only bites real soft to ask me to leave her be. usually she moves away from me and stays away unless its treat time. this lone scaredy cat is not helped by
the fact 5 other gliders are all over me, crawling, eating or sleeping.
