Okay, with my limited knowledge/experience, my opinion shouldn't really count
So I think both of these cockerels are somewhat misrepresented in their pictures. I like the black one for his nice solid legs, (haha this must come from my years with horses), nice tail feathers and I like his head/eye. If this guy were to stand up Straight and proper, I think his tail angle might be a bit low, but I think his wing would be parallel wih his nice straght back. He would also appear more balanced.
So with the blue cockerel, it's just REALLY hard to see much with the pic. It looks like his chest is filling out well, unless it's just that he's so front-heavy that it appears that way. His tail appears to be nice with decent angle. In this pic, his back looks short.
I tried to get some pics today and I must say, chickens are very dificult to get good pictures of!! Sheesh, they're always eating, scratching, pecking, pooping or on high alert. And just when they settle down and you're about to get some good shots some kid, dog, hubby, tractor goes blasting by sending them back into high alert.
