Hello Shawn. It's difficult to know why glider do not have joeys sometimes. If they are well fed, are not stressed and that their cage is big enough, there should not be any problems. One thing to considere though is that they may have joeys and lose them each time for a reason or another (some couples are known to systematically eat their joeys in pouch, there can be multiple reasons for it such as inbreeding if the parents are related or simply because they cconsidere the conditions are not right to raise them.
