Though not new to chickens nor Cochins, I am new to bantam Cochins and the MF & calico colorings. He looks very nice, with good MF patterning in front as far as I can tell. His chest needs to round out some as it still looks less full than optimal, but he is only six months old you said, right? His fuller/complete rooster coloration should also fill in over the next few months. I am surprised at how much red he has on his back and tail feathers! Wow. I would normally assume some black would pattern in? I guess this is the fun part of these cute little birds! It is kind of a guessing game!
Yes, I guess he is a late bloomer, which is OK. I hatched him the January 27, so he is coming 7 months old. he always made me think he was a hen....but every day he gets more masculine. Plus he also gets more red in the comb. Here is a pic of his back, lot of red and little black. I am hoping like you said that he will develop more and also get more color in the months to come. He is a peaceable fellow and I enjoy him being around.
Thanks for the input.
