I have 4 gliders, female just gave birth. Do I need to keep her and the joeys separated? If yes, for how long??

I’m wondering the same. We have 4 and one female is large with twins now.

my understanding is mommy and daddy should stay with the joeys.
I think unneutered males together is a bad idea. The alpha male may not let other
males joeys live, if I'm correct.

I don't do joeys, so I don't read about them much. many websites have information about raising joeys.
