Others say that what matters most is the color they are after they molt( not full true color till 2 yrs old) Like you said it will be interesting to see how the colors mature.
My Ducks all have dark bills and good neck rings, except for 1 she does not have full neck color and the muddy bill.
If you were picking today, the girl in the front right looking at the camera, would she be a cull?
Also I wanted to open the discussion up to the notion that the color genes actually comes from the male? Or so I have read
Which line of Holdereads WH has better egg production?
Which birds seem truer to size?
Any comments from all you Holderead WH owners
Regarding the inheritance question, it's true that the gold vs silver phase will be determined by what gene comes from the father. I can't use all the correct terminology but I'll try to explain what I know.
On the segment of the genes that code for silver or gold, the male inherits from both his mother and father, while the female can only inherit from her father. It's like the X and Y in people, Women are XX and men are XY so the genes on the "leg" of the Y that is missing on men can only show what came from the mother. On the genes not on the "missing leg" segments it will be the dominant genes that show through regardless of whether it came from the mother or the father, (or for a lot of traits it will be a combination rather than a dominant or recessive choice). With ducks its the females that are missing a "leg", the males have that leg from both the father and mother. The Silver gene is dominant so a male can have a recessive gold gene and still be silver.
If the drake had a silver father and a gold mother he could produce some female gold offspring as well as silver daughters, but all his sons would appear to be silver if his mate is silver. Half (or was it a quarter?) of his sons would carry the recessive gold gene like him. A silver drake with a recessive gold gene mated with a gold hen could produce some gold sons as well as daughters.
You can do sex linking if you have a gold drake (which would necessarily have the two recessive gold genes in order to show the gold phase) and a silver hen (one silver gene), because the females could only inherit the gold gene from the father whereas the sons would get one dominant silver gene from the mother and display silver.
Sorry if that sounds confusing, I had to sit down with some books and study and chart this all out for a few months before it stuck in my head and its still a little fuzzy.
