Heh. I just read that on 2-3 sites from people that breed / own them, so I thought it might be accurate, but I guess you can't trust anything you read online. :/
Here's an updated pic of one of them tonight. I tried taking pics of the whole litter and only came out with 2 good ones.
Here's a pic of one that I think may be solid mink (possibly)


Here's the whole litter confined in a bin. I think you can see all 4 of the hairless, although some are moving.


Either my sexing skills or my luck is really bad as well.. From what I can tell, all the males are hairless and all the furred are females. Now, I may be mistaking some "sagging skin" on the hairless for being males, but I figure I'll find out for sure in about a week. My other litter was not this hard to sex. I'm almost positive none of the furred rats are males though.

Also, the hairless are loosing hair each day. The one in the pic has the least and is smooth on his sides and back but the others are loosing hair as well. I'm considering keeping the darker one (near the center on the bin pic) and one of the lighter ones that has a white blaze.
