Thanks! Unfortunately, it appears my first female died while giving birth, so I'm not sure when my next female will be ready (just got the rats recently). I currently have one male and two females per drawer of my rat rack, with only two drawers set up. I'm talking with someone about getting 8 females, and definitely will inquire about whether they leave them together or separate! This is all new waters for me, I'm hoping to be able to get it figured out and at least start producing SOME of my own food!
