Clare,Is this just juvenile feathering Harry? I had a pullet in 2010 that was quite mottled as a juvenile and lost all of it by the final juvenile molt.
How is the leg color?

The leg colors were right but the birds would have scattered white feathers in the permanent plumage. It may have been another pattern type gene than mottled but simular looking. I dumped the parent black stock which I bought two years ago since there were more than just one issue with them, luckily I never introduced them into my flock. I bought some chicks from Paul that had my lavender lineage so I hope they can help but I have hatched a good amount of my own stock to get replacements this year. I got them from Paul just incase my year was not successful.
