because I'm putting them in a box to let them breed but after that do they stay in duplicate cage? Or does the male and female hamster jump back to where they are before? please oblige me asap, as I'm hoping to breed them soon.
Well, they should be separated because the mother can eradicate the male actually.
They should be in seperate cage immidietly after breeding unless they are dwarf hamsters, in which case the father is usually fine to even assistance raise the babies. But after the babies are born the mother can get pregnant again really quick.
Answers: Seperate them immediatly after breeding. Not doing so will result in fighting or death of one of them. Put them within different cages and the female will be less stressed and more probable to have healthy babies. Good luck!
