Crowing
No, I was going to but my Rainbow rooster bit the big one before he had a chance. Based on how Bertha lays eggs, I am tempted to skip all the fancy breeds at some point and just have CX over Rainbows, they are a true dual purpose bird and with the increased body mass they seem to tolerate the cold, like it is not there. As they said earlier my concern is heat in Summer.
The only thing I could see as a 'problem' with that is feed conversion. My rainbows eat A LOT! That may or not matter to you but it is something to consider
