My knowledge of color breeding does not extend very far beyond BBS and I know the blacks in BBS have a silver base while other blacks can have a gold base. I know that blue dilutes black to make blues but how two blue genes dilute black into a spotted pattern I don't fully understand except that it is different from paint or mottled patterns. I just stick with BBS and then I don't worry about color surprises.
I am still learning how harlequin genetics effects blue genetics in our ducks since I got some of those genetics in my Australian Spotted ducks, which Dave Holderread told me is desirable for producing the most striking colors. Now I can't tell which color my yellow down ducklings will end up as adults - I had assumed silverhead but now I have seen two drakes with white background color (one from my flock and one from a friend's flock, all from Holderreads) end up with green heads. My understanding is that bluehead (blue striped down, black head on drakes and blue spots on hens) is a dilute of greenhead (black striped down, green head on drakes and brown spots on hens) and silverhead (yellow down, silver head on drakes and silver spots on hens) is a dilute of bluehead just like in BBS breeding but I don't understand how the harlequin genetics produces a white background color with any head color. In general, the spot background color of the hens dilutes from brown on greenheads to tan on blueheads to beige on silverheads but I have hatched hens with white background color and dark spots that Dave said had harlequin genetics when I asked him. Since they have yellow down I assumed they were silverheads but now I have no idea what color they truly are since color is based on the head color in drakes and spot color in hens. We raised out all our yellow down ducklings thinking they were silverheads last year but this year we sold all our ducklings, including the ones with yellow down. The variations in color add to the appeal of the Spots but I would like to know how the color works - it looks like the Snowy color in Calls that comes from the wild type color so I wonder if it is the same color breeding in the Spots.
Anyway, back to chicken colors! Lol. I can only assume the silver hen has a silver base because her father was splash and she is what I call silver colored, though there may be a more accurate term for her color. I am assuming this rooster is out of her since all the rest were solid red with dark tails (I don't remember if they were black or blue since I took them to the auction instead of selling them). If he has a red base from his father and a silver base from his mother I don't know which would be dominate. I thought color crossed from mother to son and father to daughter (in sex linked colors anyway) but the boys clearly looked like their father except this one.
I should not be more attached to this rooster than the rest of the boys but I really like him and I was hoping he could live. I love the pullet colors so I am hoping they all give me blue eggs. If they are what I am hoping for I will hatch out more, otherwise I will be selling the Quechua rooster too.
