I'm wondering how I ended up with a lemon blue color in this roo (no crowing, yet, pretty sure it's a roo) that hatched from a d'Uccle egg in July. I had one white Sultan bantam roo, and the d'Uccle hens I have are porcelain, white, and mille fleur. Which hen could it have been? This is lemon blue, right? It's definitely not black...it's darker than my blue Polish, and it almost looks like it has a brownish-red undercoat to its feathers, if that makes any sense. Whatever it is, I love it and he's a keeper!
