I have a question about bill color genetics in Khaki Campbell ducks. When you breed for the black bill in female KC ducks, when does the color become apparent? Can you tell at hatching? When fully feathered or later? Is the black color recessive or dominant or incompletely dominant? I read the bill color genetics section of Holderread's guide and the duck genetics sticky, but I didn't find an answer to this question.
I have a 7 month old KC duck. When she hatched, she had a light pink bill of uniform color. As she has aged, her bill has gotten darker, it is now about the dark pink-brown color of mud or coffee with cream. It is still uniform, no saddling or color variation. I have a KC drake with good markings & color and a classic blue bill. If I breed them, can I expect any hatchlings to have a black bill? How old do they have to be before I can determine their adult bill color?
