6 months ago I picked up a hairless rat female from the pet store to incorporate in my colony. She's nice enough and she has good weight. I made sure to take my time getting her to weight before her first litter.

But out of 2 litters she has had about 28 babies...and only 7 have survived their first few minutes. I don't know if they're coming out dead or what, as I don't get all up in there and watch.

From what I've heard from others, this sounds like this is pretty much on par for hairless rat moms. Anyone else had similar experiences with hairless?
