columbian restricts the color to the end, like you see in the patterning of light sussex for example... this thread is about crele, not columbian. i have a blue crele oegb roo, and in researching what color he was, i discovered this wonderful 'rainbow' coloration.
cuckoo and barred alternate color/white/color/white. the exact mechanism i don't know exactly, but a slow feathering gene gives a sharper contrast since the on/off isn't instant. with faster feathering breeds, since the on/off isn't instant, you end up with fade in/out to white/color, resulting in a blurred area between pure color/white. i say color since crele takes the base color of the feather, while a true barred or cuckoo bird is white barring on a black base. (i believe)
and in researching the dorking (my LF breed of choice) i found that it also came in crele once upon a time, but doesn't seem to exist much in this country... so now i have a goal.
edit: actually i just found a picture of crele dorking, while not even looking for it! LOL clicking the picture will take you to that website...
