I am not familiar with these colours and I have just hatched a lovely batch of cochins. Some of them are pitch black with tiny white bits , others are black with white wing tips, white bellies and white on the face (look like spectacles almost) and some are a light bluish colour with white as well. Cochins just melt my heart they are SO CUTE! Those fuzzy feet and butts!!! What are the adult versions of these going to look like, sorry still working on the pics! Will get some on asap...
