Haha! If they are not perfect they are out of there! Lol I get a little worried when I see stuff like that this early. Blaze has complete shoulder pattern with minimal color on chest. He has some but not a lot and no shafting. Shame he is a bad boy.you are just on such a high alert . he still young ,the white will goes away for sure .his chest look great to me . will become more tidy and define when he grow older .
if you have better younger cockerels then him ,than it is ok to dismiss him .
you are ignoring how gorgeous is his copper and how advance is his shoulder coloration .
don t panic let him do more growing .
cockerel with early shoulder coloration will give daughter with a complete hackle as young age 6/7 weeks .
there is relation between shoulder coloration and chest marking ,both are controlled by Autossomal genes ,
chooks man
