It's possible that if he did just throw them together without an introduction that the male may have killed the female. The males can be very aggressive when they mate -- it would be best to neuter hima nd try him with another neutered male or female after very SLOW introductions.

If he's an adult male, you can't put a baby girl in with him, unfortunately, he needs another, grown, glider.

Also you need to realize that breeding gliders is HARD. It seems easy and like a way to make some extra money, but they have a lot of very special needs. My rescue took in a group of five gliders that were mixed sex. One of the three females was pregnant with twin joeys. A week after they were OOP, she dumped both of them onto the ground.

For the next four weeks I was up every hour on the hour, around the clock, handfeeding joeys. One still failed to thrive and died. The remaining glider required round the clock care until she was finally old enough to go to her new home.

Not to mention that not knowing the background and lineage significantly increases the risk of sick and malformed joeys. If you don't sell the babies, do you have room to keep them in a separate cage? And to neuter any males that result so they don't interbreed with their siblings? Do you have a glider savvy vet? If you end up with 3 females do you realize you're required to register with the USDA as a breeding facility and be inspected regularly?
