Darker red on the wings, or generally a wilder, splashier coloring are roo traits. No, it doesn't work for a lot of breeds, such as breeds that are solid colored or barred, but for mixed breeds and easter eggers it's a good rule. Look around on the threads on sexing by color, or just the what breed is my easter egger thread. You look at enough pics, you'll develop an eye for a roo and a pullet coloring.
He is lovely. Why do you have to get rid of him? I love all my roosters...so much colour and beauty .....and very interesting to watch their behaviour. Also he will protect the hens.
what was the result cause mine is almost identical but is a hen at 12 weeks. Some hens have that fat rose comb. there are no waddles growing. interesting
He also has pointed shiney feathers starting infront of the tail and accross the shoulders. I always go by the absents or presents of the saddle or also called sickle feathers, they are always long, thinner and shinier than other feathers, and yes on EE's usually a different color than the other body feathers. Alot of times they will be shades of red or orange. The hens will always have short round feathers on their backs, tails, and shoulders.
You really should keep him and buy the No Crow Rooster Collar. I absolutely can NOT have a crowing roo where i live and this spring my Silver Penciled Rock turned out to be a roo. Hes such a great roo i got the collar to try from "My Pet Chicken" i have to tell you the collar is 100% effective!!! Mine no longer crows at all!!! He still eats, drinks, mates, and does everything else normally. Make certain you buy the correct size and follow directions to a tee. Watch a YouTube video on placement . A pinky of space should be between the collar and skin. I watched as mine went through the motions of crowing the collar will slip farther in place and stop the crow. With my rooster the crow is stopped completely. You should give it a try. This way you can keep your rooster.
