My long term goal is to have a BEW project, so I'm trying to learn all I can now. I know that shaded/chocolate/lilac should never be breeded into a BEW line. But what if let's say, a black bunny with chocolate somewhere in it's history gets breeded in? Does that also cause the ruby cast or have the chance of causing it? If so, how do you go about avoiding picking a bunny with that in their history? I have a pet lop who is a VM black and pedigreed, and his history on the pedigree only goes back a few generations. Is it 'okay' if those colors are far enough back or does it run the risk of ruining the eye no matter what?
