I had someone ask me today if the mom dies that has joeys can they be placed with another mom that just weaned a joey?

I am only a small breeder. I have heard of someone else trying it, but I don't know the outcome.

Hopefully someone with more breeding experience will see this.

It would be a risk. If it were a situation where they were in a trio, and there was another female currently nursing, it would be possible that she would take care of the remaining joeys. However, supplementing would possibly be required.

If it was a normal breeding pair, I don't think I'd risk trying to put strange joeys in a cage with another mom. I don't know that this would work.

I know of a few people that used a 'surrogate' mom for their joeys and it worked great. There was one other that the mom took it but dad did not.

Would depend on the gliders really and I would make sure the joey smelled like the new gliders introduced to as well.
