Has anybody done this? I have a white crested black Polish roo and a buff Cochin and a Black Cochin hen. I am curious about gene dominance with the crest , comb, color variations and feather legs. What shows up and what dissapears? Does anybody know ? My chickens are young, my roo looks very busy and about half of the eggs I have checked appear fertile... I have to rehome the roo soon as he is an all day crower and we live in the burbs. As I hatched him myself I'd like to have at least one of his offspring around, hopefully a hen this time. Thanks in advance.
