I breed b/b/s silkies. In the 1st batch of eggs I hatched 2 years ago I hatched a light buff hen (don't have her anymore). The eggs I bought were supposed to only be b/b/s. I now have a 6 month-old roo (probably from her). He is an off white color, with a few buff and black feathers coming from back of hen. He has a perfect comb, almost no wattles, extreme feathering of his feet. I don't name my chickens but I have named him "Fabio". He is GORGEOUS! If I want to keep him for breeding, should I keep him with my black hens to override the color? Hate to get rid of him...Thanx!
