Hello, I am trying to figure out breeding "rules" for bantam cochins. My son has a black cochin hen and a blue mottled hen. The colors we are interested in are blue, black, splash, and mottled. Is there a book out there somewhere that would explain what breeding one color to another will produce and what should not be bred as it will/may produce a funky color? I am very confused on what is being looked for in the mottled as well. Is it some sort of percentage of white? Sorry to sound so stupid. Any help is appreciated.
