My Barred Rock chick Zoe is 8 weeks old and her older brother Gabriel is 13 weeks old. At four weeks, Gabe had a comb and wattles larger than Zoe's is at 8 weeks. This baby is making me sweat, typical of some of Lexie's kids since she was a cockerel-colored pullet herself that broke all the BR sexing rules. Zoe here is a fence sitter, I guess. Here is Zoe today: Compare her brother Gabriel at four weeks then at six weeks old, two weeks younger than Zoe in the above pics: I'm thinking I have a late blooming cockerel or just one that didnt develop quite as early as its brother. What do you think?
