I'm not going to breed rats on a larger scale until my hubby and I have our own house. For now, I have two females and will get a male as soon as they are old/big enough to breed. So my question is this. One female is a blue berk. I am unsure of her age, but I would guesstimate her to be around 3 months old. She weighs 280g. The other female is much younger, maybe only 2 months old. I know I should wait another month for the other female to mature some more before breeding, but if I get a male when she is ready, and I move her to his tub, wait a few weeks and then move her back, will she be ok to raise the litter with the younger female in the tub with her?
