I just weighed all the girls. My two black and white females are 23g and 27g. They are being housed with their female offspring. The 3.5 week old females (agouti) 6g and 8g. The 4 week old albinos are 11g and 17g. 4 week old agouti girl is 12g. So that's 5 new females. I'm going to pair each albino with one agouti and I'm going to get one new females of a different fur color (I like to keep the females easily identifiable) so I can make 2 new breeding groups. The left over agouti female I might feed off. She's only 6g at 3.5 weeks old. She was the runt of the litter.

But that still leaves me with two new groups. The new groups will be breedable in the beginning of November.
