finding out the bunnies sex

Question
I have an 8 week old calico rex bunny , I was wondering how long before you can find out the sex of the bunny.

Answer
Hello,

You can actually do it at birth, but it's difficult then. I think this is something you need to see to understand, so I'm going to include a link with images. Good luck!

Also, Mini Rex or Rex actually do not have a "calico" variety.  I would be interested to find out what he actually is. You can visit: http://www.nmrrc.com/Varieties.htm to see all of the Mini Rex varieties. Rex are much larger. You can visit: http://www.nationalrexrc.org/Varieties.htm to see all the Rex varieties.

It's interesting to see how many colors they come in!
