Some people say you can tell really early from the head spot, and the boys are a lighter color than the girls tend to be. My babies are one week old and I think I can kinda see signs already, but I want to see what you guys say. 1. This one is actually a dominique: 2. 3. UPDATE: They are now 5 weeks old and fully feathered. What do you think now? (The pics are in the same order as the ones above.) 1. 2. 3. To me, 3 is obviously a roo and 2 is obviously a pullet. The dom has the coloring and body shape of a roo, but his comb is just barely red and his wattles haven't really grown at all like the BR roo. I think he is a roo, but how long will it take for his comb and wattles to develop?
