Can you leave baby girbils in with both girbils?
If you mean can you leave mom and pop both in the tank with the
babies, then yes. Dad gerbil will be "sent to the couch" for a few
days while mom looks after the litter, but he will be welcomed back
and start caring for the pups with mom. When your gerbils are at
least six weeks old, you can then separate them from mom and dad
and into their separate sexes.
