spaying/neutering my rabbits

Hello everyone

I'm getting two bunnies soon, a male and a female, from the same litter. I want to house them in the same cage but don't want babies.

I don't even know if they would do that being that they are from the same litter but don't want to take the risk. Should I house them in separate cages until I can get them both spayed and neutered? How soon can I do that? Will they be able to bond if they aren't together?

Any help please
