Hm., At 7 weeks I would think the comb would be at least pink if not red by now! Though the posture looks male...I guess I'll say gender neutral as of now!
No one really knows with cochins, it takes them a long time to mature. Just by guessing I would say a girl because your bird in the back has a much redder comb.
it came from McMurray - so it is not a bird from a breeder, so the color could be poor in quality?
they don't list Birchen as an option.
I will hang on to it for a bit longer to be sure. I don't have a good set up for feather footed friends <G> in the rainy Pac NW.
you guys are great, THANKS
