Hi, no, they are not hermaphrodites, they look normal. The breeder's information is just a guideline; it just takes a few weeks longer sometimes, you can't always go by the info provided. But everything looks normal.
PS. I've also had some that just take 3 weeks longer. Right now, I even have an automatic that is 17 weeks old and still not finished, and according to the breeder, it only needs 12 to 14.
Don't worry, everything is fine with your ladies, and they'll be okay :)
