Should be warm, not too hot, and not cold. leave them in the nest, no matter what. you can look at them, but don't touch. just leave them be, the mother will take care of them.
many animals especially gerbils enjoy company of their own kind and if you don't want baby gerbils the same sex keeps that from happening.
I'm not posetive, but if I were you I wouldn't, it wouldn't be very healthy.
they ill eat on there own
Baby gerbils can be sold about a week after the next litter comes, at around day 35.
Baby gerbils need their mother's milk and should not be given anything but kitten replacement milk and only if something happens to the mother.
No less than four weeks of age.
Male gerbils can be neutered, but it is not recomended. Female gerbils should not be spayed. In general male gerbils should not be neutered unless there is a good reason for it.
Not unless the parents are.
My baby gerbils have already started eating sunflower seeds and drinking water and they are 25 days old.
Gerbils should not be separated from their mother until at least six weeks of age, since they still have many gerbil behaviors to learn. Gerbils taken from their mother before then can suffer from not being as friendly or healthy as they could be.
No. You should leave the new gerbils, mother and father together. If the parents seem to be harming their children you can take the one harming and separate it using the split cage method.
Gerbil pups should remain with their mothers for at least six weeks, if not eight, even though they are weaned at week four. Gerbils still have many behaviors to learn, and separating them from mom early can lead to gerbils being aggressive and untameable.
