I’ve got two barred rocks and I know one is a female and another that I’ve been suspected is a roo since week three. They are my smallest and largest chickens respectively. The suspect has more heft to her/him, noticeably larger feet, bands look bigger, holds its tale higher up, walks more proud, and just barely larger comb and wattles or more noticeable. They are 7/8 weeks old. First set of photos is the female for contrast.
