Ok, I've been breeding d'Anvers for a while and this one is leaving me puzzled. This little guy came out of my solid (black/blue/splash) d'Anver breeding pen. It is noteworthy to mention that my solids have been outcrossed to my Quail d'Anvers in the past for fresh blood. This usually results in an occasional Quail chick out of the solid pen from the residual genes from the Quail ancestors. This year, however, I got something completely different. It is a black chick with dark red tipping on all of its down feathers. The front and underside looks exactly like the top. Some of the feathers coming in on the flights appear to have a slight amount of stippling on them, but are mostly black. I'm really baffled, because I've been breeding d'Anvers for 18 years now and never had one pop up like this. Any ideas?
