Feather color on Blue Wheaten Cockerel

[Holiday Hatch]

Members of the Forum have told me before that Wheaten & Blue Wheaten Cockerels are late to mature.  I'm trying to cull a few of the ones I have that are 6 months old.  Is this still way too early? 
A couple of the Cockerels have some red/gold feathering among the gray feathers in the low back abdomen, beneath the wing. (I don't know the proper term for this area)  Is this feather color okay or a disqualifier?  Will the feather color change to gray later on?  Thank you for the help - Linda

Sounds pretty minor.   I would be looking at things like shape, weight, thriftiness and vigor, comb, muffs, tail carriage, body carriage, knock knees, crooked toes, beak length and shape, and probably a few others before worrying about a few gold feathers in the blue sections at that age.

Mike - I appreciate the suggestions on what to look for; that helps.  There is so much to consider.  Thank you - Linda

orange red ticking in the fluff of the body and stern is permissible

Regarding things to look for on Wheatens/Blue Wheatens, is six months enough time to determine shank color?  How long does it take to develop a good slate color either in the pullets or cockerals?  I see a hint at six months and am wondering if they will darken any more later?
