it's possible they have split wing, but I wouldn't judge that until they're fully grown, because they could just be moulting in new feathers too...
the crested is the roo, the other a pullet. both are blues, so breeding them you'd get half blue 1/4 splash 1/4 black based...
as far as reading up, there is no 'set' breed standard, but what has been proposed for the breed group I'm trying to organize can be found at
www.sfhusa.com
the website is still a work in progress, and notifications aren't coming to me properly, so if you'd like to join it let me know (pm) here...
but if you read back in this thread, I posted up the possible color combinations and what they might be genetically, but that has nothing to do with 'proper' breeding or anything.
in a nutshell, basically you want yellow feet/legs, single comb with no side sprigs (it's ok for the comb to be wavy in crested birds) and all birds must be mottled regardless of the base coloration (splash may be harder to see mottling) and best to avoid issues like split wing and any crookedness in the body at all (scissor beak, crooked toes, wry neck/tail, curved keel bone or spine, etc).
