In addendum to what I_Love_Hamsters said, since you've already taken the male out, it's probably a good idea to keep it that way. Depending on the hamster personality, the female may get very violent towards her mate if you reintroduce him. Some say they can never get along again, but I say it depends on the hamsters-- mine were both very laid back, so after the babies grew up, the female was ready to accept the male again.
Good luck with the little ones! 
Oh, PS- if you haven't had a large amount of hamsters before, they ARE a handful once you get past ten.
>>My sons Roborovski hamster has had babies. We thought she was looking "plump" so he has been checking everyday and he found them last night, 5 of them. My question is, I've read conflicting advice as to whether or not the male should be removed. I always thought you should remove the male so he doesn't harm the babies. But I've read that if you don't mind more babies, he will help bring food to the nest and keep the babies warm. Any thoughts? As of now, he has been removed.
