Pretty sure he's a roo, but of what breed? Other chicks in picture are Dark Brahmas and one Jersey Giant of the same age (about 3wks). He has a straight single comb, is very slow to feather out and is smaller than the Giant and Brahmas but still a LF. Chipmunk stripes on his back still. Much darker than the RIR I had last year (and they were dark for hatchery quality). Spunky but not aggressive.
