The way I've done it was to test the offspring of various pairs even switching roosters from one hen to the other and then continuing the line from whichever tasted the best.
I selected for flavor in the meat without any seasoning knowing that if I already know the meat is high quality I can...
If anything it'll make it tougher in the roosters, but if the genetic percentage is low enough it won't make a difference tenderness can be selected for.
#1 stayed where you put him, which indicates he could be easy to handle, plus I prefer the clean barred color. Colorwise I prefer #3 over #2. I do think ease of handling is important, but that could all change as they mature.
