I have five EE's with that comb and they're all laying now....I tried to sell one as a roo, glad I didn't have any takers! Had 3 really pretty boys so nobody called on the black one....thankfully because I get a beautiful blue egg from her!
Edited to add that I looked closely at all five of my girls that have similar combs tonight and really only one has that distinct 3 comb, and she is the one that lays a pretty blue egg. It's merged more then it was but the others have turned more into a traditional pea comb but I do remember counting rows on them when they were younger, trying to figure it all out.
I'm learning to just wait for the egg or crow......
