i bought three hamsters form pets at home and they sed they wer all males, now one has given birth and i dont know whether to take the two males out but then it says on some websites that the male is a key role in the up bringing in birth??
Take out the males asap. The males will eat the newborn cubs. Also, put each of the mother hamsters into their own cages. Leave the mother and babies alone for at least 3 weeks. Do not remove or clean the hamster litter from the mother's cages. If needed add a little bit of clean litter at a time. Isolation is key to the survival of the cubs. I've raised several litters of hamsters. Just keep the mother or mothers fed and make sure she has enough clean water. The males hamsters have a "V" shape backend. The female hamsters have a "U" shape backend. I hope this helps.
