Whats wrong with them?

I'll get pics when I get home. There are a few babies from my foster litter that are almost hairless in a way. They are weaned but have very thin hair and you can see the skin. Could it be caused by poor nutrition being the "runts" of the litter mom was already caring for that was about 1 week older?

They're probably either going to be hairless or rex. The hair may come in and when they molt, fall out again, or it will just all fall out and you'll have nekkids. :)

I'll go snap a pic in a second

I'm still not used to my rex's. I just know that people are going to think I have defective rats. lol.

Heres one of them. Out of like 100000000 pics, this is the only one that cameout.

What do you think?

Give her a break on the breeding man. haha, I have no idea buddy, sorry.

This one is from the momma that prolapsed Jimi. I had to put her down and leave all 16 of her babies to the other moms. No more baby rats around here for another month or 2.

Looks healthy, and looks like it will be hairless.

If the babies are from a rex/rex mating (If I remember, the mom was rex? Or maybe it was a different one...), they're probably homozygous for rex, which is what makes them look all nekkid! :D I love me some nekkid rats.

Mom was a rex and dad was not rex. the 2 other rex (moms siblings) that bred as well had no Hairless in there 2 litters. How could this be?
