hey guys i just wanna ask , my sugar glider's baby , i do not know how old but its living with its parents happily in a big cage

im just wondering should i start seperating my joey cause i saw it started chewing fruits as its parents took it back to the hammock for it to eat . so is it fully weaned from her mother ? but i think its still not strong enough to climb , im new to having babies~ so i need some advice and should i seperate the baby and use new short cage cause i scare it try to climb and dropped to death T.T
