From what I've read, Campbells fathers are good parents and will help to raise the young with usually no problems. Of course though they'll probably get the female pregnant again straight away so successive litters are likely.
I remember hearing a way round this - separating off a section of the cage with fine mesh so the pair can still see and smell each other (so reintroduction shouldn't be a problem) but can't mate so delaying the next litter.
Babyboos will have proper answers for this though
