Hope this is okay to do here.
There's a lady over at AC that breeds them. I found some of her post for you.

She has a awesome room set up for breeding. The pictures in that thread had been removed. I'm sure you can search her post and find out a lot of info on them. She's a nice lady and i'm sure you could shoot her a pm and she could answer any questions for you.
Whatever you learn about them please bring it here so we can learn too!!!
