I'm pretty new to gerbils/breeding (six months), but....My guess would
be about six weeks old. Although I've noticed a great variation in size
just with the 13 pups that my clan has birthed. If he's been out on his
own for a while he might be older (i.e., smaller than normal). If it is
a boy, I've noticed that the boy-parts look pretty prominate at 6-7
weeks before they get covered up with fur and sexing gerbils gets hard
again.
