And I suppose you're right with the time span. I'll see if I can find some plump, healthy looking rats when I go in tomorrow to pick up the PK smalls for my big girls (they kill them for me since I don't have my CO2 chamber sealed up yet). I have two open mouse tubs since I fed off my other two trios that I can house the pairs in.

Thanks!
LOL, thanks! I suck at math! If you can get just weaned rats, it's really just so much easier to deal with the moms. No claws in your hand, no slices of skin missing when you pick them up lol. Ouch, even my tame ones have some killer toenails.
