hey there

At the moment we have 1 big cage that all the rats roam in and 1 where I put the females once they look like they are pregnant to give birth until they are weaned. Theres usually 1 or 2 females with litters at a time in there.
I am wanting to up the amount of babies we have so we can have more for our snakeys to eat and was wondering if it would be best to get a couple of tubs and do a 1 male to 3 or 4 female ratio instead of what we have going on now. Or would it be pretty much the same results with more space taken up to to the extra tubs?
