Buff is still my favorite color, but the LF buffs aren't nearly as close to meeting the breed standard as blacks. Buffs are too fluffy/soft feathered and their egg color is generally a bit too greenish. I'd given up on them and last year decided to work on them some more. My LF blacks have great size & type and lay large to extra-large very blue eggs, so as I've done in the past I decided to cross them into my buffs again. It would have been nice for this project if my blacks carried gold (s) and there may be some in the flock that do, but the the cockerel I used was pure silver (S/S). It is a sex-linked gene, so all his daughters are pure for silver (S/-). He was crossbred with LF buff laced Polish pullets and outcrossed with bantam buff Ameraucana females. The photos of the F1 females are posted, below. This year I'm using a LF buff cock over both of these pens of pullets. I'll only raise up the pullets and I should be able to sex them as day-old chicks, due to the sex-linked silver gene. The pullets should be buff (gold) like their daddy. The cock is also being used over 3 LF buff hens, so I plan to use the best pure buff cockerels from them over the best pullets from these two cross projects next year.
I expect it could take years to get back to pure buffs, but such is life.
