Female or neutered male? We got Bill as a rescue almost a year ago and were told he was a male. Never gave it a second thought until I purchased 2 babies a few weeks ago. Bill's definitely not an intact male. There is also no gland on his forehead. Sorry I keep referring to Bill as a he. That's just what I'm used to doing. No clue where the picture went if it's not here it on my profile.

I am not seeing a pouch - it is likely he is a pom off neutered male.

If he has not had a well check up with a glider experienced vet - you could take him and have the vet tell you for sure.

Are your babies male or female? As long as you do not put an intact male with "Bill" and later find out that he is actually a she - it really does not matter.

Just make sure all of the gliders are healthy (vet check up and fecals) before you do introductions - and if the joeys are small, they should be about the same size as Bill before you introduce them.
