I just bought a number of "exhibition Faverolles" and want to get back into breeding them. I got birds from one line but they grew out to have white earlobes, so I sold them and bought others from a different line. Turns out they have white on the earlobes too... I really don't want to get rid of them as I invested a lot into getting top bloodlines. Instead I want to try to breed out the white, has anyone been able to successfully get rid of this defect? How difficult is it? Any advice is greatly appreciated.
