    The males parts will be visible at weanling time. Just flip them over, and give there belly a little push, and bam ther either male or female.

    Re: Sexing rats what age

    You can tell male/female at day 3. I judge by the genital distance.

    Re: Sexing rats what age

    Yup, before you really learn what your looking for, the best way to learn is to hold 2 rat butts side by side in the palm of your hand, lift their tails and judge the distance between the anus and genitalia.

    Once you figure you have a male (longest distance from anus to genitalia), it's easy to just compare side by side until you can tell at just a glance.

    My males are usually very prominent by 3 weeks of age.

    Re: Sexing rats what age

    Re: Sexing rats what age

    Oh yup, sure are. If I didn't think it was dirty to post pictures of, I would. There are a few websites with side by side pictures. Just google "sexing rats" and you should get a lot of hits.

    Re: Sexing rats what age

    Before their hair is fully in you can tell your females by their obvious little nipple marks. Once they are ready to wean at about 3.5 to 4.5 weeks of age just dangle them head up (sort of under their armpits). Those with dangly bits are your boys, those without dangly bits, those are your girls.
