Yes that's what I would do. The breeders will last almost a year, until the output drops. Yes, you can replace with babies. I never did Norways, but ASFs grow slower. When they are breeding, they get nasty. Ive been bitten to the bone before, its no fun. They smell way less, about the same as Gerbils. Watch what you feed them Mazuri lab block works best. They will eat the babies if the fat content is off. Sometimes they will eat the babies or turn on each other for no reason. Ball Pythons love em, and the size is good. You can always feed your big females 2 if need be. Watch for chew outs, give them a small block of wood to chew on. A wheel will also keep them busy.Let me know if I forgot anything.
