Well truthfully, I don't like mottles and splashes as much (there was a time when I would not keep any of them). I'm starting to soften up to them a bit though. I'm not breeding for anything in particular really... at this point it's just a curiosity thing to see just how white they will get. Breeding for some certain amount of white or color distribution in mottles is very difficult because these birds are born solid red or yellow, and then when they molt some of those feathers are replaced with white ones, and in successive molts more white comes through. It's not like pied or splashes which have the white feathers from the beginning.To my eye they are beautiful, nice shape and stance too. Are you breeding for more white, less white, different color distribution? I don't know about mottles
