Mottling works similiar to lavender. It takes two copies to produce a fully mottled bird. My mottleds are probably not the same as yours. I decided not to use any mottled birds from the lavender project. I used Speckled Sussex to get the mottling for this line, crossed to black orps. After a couple generations, selected the most solid mottled birds (without signs of red) and bred them back to black orp again. The split mottled parents were showing great size, so I'm anxious to see how these fill in and of course, how the color turns out. I'll try to post updated pics as they feather in so we can see how it changes. From everything I have read and seen, mottling seems to have a mind of its own and varies quite a bit from bird to bird and line to line.
