Ok. I have breed mice before. So this may not be the same as Hamsters but here is what I know. Out of two litters we had 25 mice. So be prepared. Don't breed them because you want one of the males UNLESS you have a home for ALL the babies. Do not leave the male in with the mother when she has the babies becasue he will kill and eat the babies. Yea yea yea I know hamster's aren't liek that, but why take the risk? Also research breeding hamster's on the web it will give you alot of information.
