I have a 5 month old sultan roo named Bubbles, and he isn't crowing yet!! he has saddle feathers, large and red comb, and will stand tall and flap his wings, but no crowing. he still peeps most of the time, and the pullets that are younger than him are now clucking and will lay soon. There was another roo I gave away as someone really needed a banty roo and loved barred rocks, (he's a banty barred rock) and the guy who bought him told me he has been crowing for a long time and the other hen the roo lives with just hatched out 2 of the roo's babies! that roo is the same age as bubbles! I do have two other roos, but they (the current roos) ignore him (bubbles) when he flaps, and are the most docile and least crowing roos I have ever seen. so, what is the latest you have had a roo crow? thanks! These pics are a little old, he's a little bigger and his comb is way larger, (he is more like 4 1\2 months in the pics) but in the first two you can see his comb and in the last one a hint of saddle feathers.
