I breed my own rats, have 3 males and about 24 females, I keep 1.2 in a tub for two weeks then move the .2 moms into tubs and put two new females in with the males. I dont know for sure if these two rats have ever been paired or if this is the female rats first litter (I bought some new females about 2 months ago), but I have about 5 small rats that look like this. The mom had normal looking babies as well, but some of them were almost hairless like these are. One of them appears to be blind, in one eye for sure, and his other eye looks odd as well. What should I do with them? I am a little nervous about feeding them to my snakes. Is hairless like this a genetic trait?
