Thanks SO much - your info answered SO many of my questions! However, I do still have a few more (and since I don't know what other breeds Golden Necks might apply to, these questions pertain only to d'uccles):
1. How does one know if they have a dominant white type Golden Neck, or a splash type Golden Neck? Can they be visually identified, or do they have to be bred to find out?
2. I'm assuming splash type Golden Necks should only be bred to other splash type Golden Necks, regular mille fleurs, or blue mille fleurs? But in the case of the dominant white type, what other color can it be bred to without muddying up the genes (other than other dominant white type Golden Necks)?
3. What would one get if they crossed a dominant white type Golden Neck with a porcelain?
Thanks again -
