I currently have one of each now, but they are only 4 months old. They have been crowing for a couple weeks. The EE is louder now, but who knows if it will stay that way.
My Buff Brahmas are now 3 months old, and it seems one is a cockerel....which is fine by me :) He will be my first rooster. First 3 pics are of the cockerel (I hope) and the last three are of a pullet.
