The female who is missing the clumps of hair is actually the dominant one. She has always been the bigger of the two, she's a bit older, and she dropped her litter first.

How long are they productive breeders for? It's only been 3 months of breeding...

If I chose to hold a female back to replace the one mother I take out (or if I simply hold a female back to make it a 1.3), is there anything special I need to do? I tried to hold a female back during December, but it didn't exactly work out... The original 1.2 was in the tub. I left a female from one of the litters in the tub and took all the siblings out. Once the new female was about 6 weeks old, one of the moms decided it was time to kill her. So one night she ate her alive. Definitely traumatized me for a while.... So what is the proper way to 'hold a female back'???

Thanks!!!
