chocolate tort baby bunny
Well, with baby buns, it's hard to tell what color they will be when they get older. It looks like I didn't guess right on either one of the colored bunnies. I think the "blue" one is actually "lilac" and the "chocolate" one is actually a "chocolate tortoiseshell". The two white ones are still white and it looks like they will be a ruby eyed white. Depending on their gender, the two colored ones may remain in the herd, the two white ones will be sold, though.
This color bunny is a "chocolate tortoishell" since he (or she, we don't know the gender yet) has a "chocolate" colored nose. The lighter color under the chocolate color is where the "tortoishell" part comes in.
lilac baby bunny
This dove gray color is "lilac" which is a diluted "chocolate" I think. A diluted black is "blue" which is what I thought this bunny was originally, but he's lighter than "blue" so that leaves "lilac". I think, anyway. Figuring the proper color of a bunny is pretty difficult! Now I'll have to go look up the genetics for these two colors, it involves a lot of recessives to get the diluted and the brown.
