If you mean baby like 2 weeks, he is small, eyes shut and ears down. Don't separate him from the mom. You can usually tell if a gerbil is a baby (this time i mean like 1/2 year) because he is still small and his squeak is high.
Like if you intruduce a baby gerbil to a female and a male gerbil they might be nice to him but the male gerbil might play fight or fight in the cage i do not think if you leave the baby gerbil in the same cage with the male gerbil or a female gerbil the female gerbil migt fight or play fight with the baby gerbil if u do please be real care full because if the male gerbil no that the babby gerbil if its a baby girl gerbil yhey will mate or if u do the same with the adult female gerbil they mate to with a baby boy gerbil or adult gerbil will mate to and also mate means that the female gerbil have babbies with the male gerbils .
A baby Gerbil
yes but only if you are expecting baby gerbils.
a gerbil is a rodent. it is damesticated and lives feril in derests
Until the mom has another litter, or until the baby gerbil can eat solid food.
Look on his back side. If it is a Female there are no lumps, the gaps between each ahem holes are larger on a male and smaller one a female. also it is like a baby kitten. the only way you can tell its balls. if it has some then its a boy.
Yes, she is probably just moving it
Because she is scared or excited and wants to tell another gerbil. Or she is calling for a male gerbil to mate with.
If your gerbil is healthy it will have soft shiny fur,bright eyes and a clean nose.
YES
no male gerbils are very caring so dont split them up
after a couple of days when have goten used to the cage
