The first picture that I posted is a male the second I posted is a female.
The inner lining of the vagina is shiny and pink in appearance and retains its vertical slit-likeshape. No penis appears as the vulval lips are rolled open, confirming that the animal is a female rabbit.
The male rabbit has a penis that is long and pointed and curves slightly. He will also have testicles like the rabbit in your #4 picture.
You need to press down on the area like they did in the pictures I posted. You should be able to tell the gender by the pics I posted and the descriptions. If you can't, post new pictures and we can help
You have to open the area as well as press and the pics have to be closer and larger. If it looks like a straw, it's a male and if it looks like a taco it's a female. Cute bunnies on the facebook page.
