Need help sexing baby rats!

Sexing rats usually isn't that hard, I have sexed thousands of them over the years. It is easier if you check them before the hair fully grows over their belly's, as you can easily identify the nipples at this time. It is usually easiest around the 2 week mark.

Females will also have an evident line between their anus and urethra.

Its a bit hard for me to make definite identifications from the photos.

Feel free to message me if you need any more assistance.

OK, it's been a couple weeks since I posted the pics, big balls hanging down on the males now LOLOL. I'm going to separate today by sex and let them get a little bigger before I breed.

Looks like you guys sexed them correctly, the two white ones turned out to be females, just have one female that is grey. I have four obvious males. I actually moved a male to the female cage, the testicles do go away when you pick them up by the tail LOL. Can easily tell if you lift their tail when they are sitting on the bottom of the cage.

Circles are males tear drops are females
