I was a bit surprised yesterday when going through all my 2 week old litters... I came across this very oddly colored baby. It's coloring is just like what you'd find on a Champagne D'Argent. Champagne's are born all black, and get all of their silvering as they mature, with the head being the last to silver. This one is a lot more silvered over the back, than what a Champagne would be at the same age. The back is very evenly colored. However on the face, it's still patchy with black, and the belly is more black. Makes me wonder if it'll silver in these areas as it matures.
It's not an agouti (no ring color), and not any kind of Steel. It's out of two Blacks, with nothing but Blacks and Blues in it's background for 20 generations. We're thinking it has to be some kind of mutation.
Will be interesting to see how this little one developes. I'm planning on keeping it to experiment with breeding it. Will post more pics of it here and on my facebook as it grows up.
