Have mutt and pure and hatchery chicks, all mixed together and trying to figure out which breeds I have. 3.5 weeks old. Some are obvious, like the light brahma and the turkens. What is this? Dark Brahma? Speckled sussex? Does the white breast signify anything in the way of gender? All the others that are more obviously SS do not have this. How about this little roo? Brahma of some sort? (I have light and dark, both breeder and hatchery).. Or easter egger/mutt?
