Good news - since Moonshiner will be a regular contributor to this thread as their project progresses with the Isabel + barring.. there will be added information and viewpoints. Yay! The more ideas, experience and insight in this thread the better it will be. Everyone is welcome to pitch in. Meanwhile, too, -- here are some things that could be concerns for this type of project: Lavender gene can cause feather deterioration - they can look shredded Lavender gene can cause a problem that only shows up in the males where some of the shoulder wing feathers appear to be "permanent pin feathers" -- as if their growth is stunted Lavender reputedly fades out over time - and specific chickens will be needed to refresh the lavender from time to time For my particular approach Cresting is incomplete dominant - cresting will have to go in my world, because I think cresting messes up the comb and the battle isn't really 'worth it' More about crests later The cream gene will need to be bred OUT and it is recessive -- so there will be no way to know it is there. What may happen down stream for me is that the golds/reds in the Isabel could be overly faded, and it could be possible that two of the future breeders could carry cream and a chick from then could get double cream, fading them too much. (correct term would be dilute).
