And, mainly, noticing that the roo that seems to be the most dominant, impressive bird only takes on certain jobs while the 2 others who are about the same as him in stature take other jobs struck me as extremely interesting. Especially how I have never seen the 'big guy' fight. I've seen him peck a small amount of times but the other two are the rowdy ones. The 'cool, yet dominant' demeanor of my main roo (who was my favorite since day one) is definitely something I would try to selectively breed for. He's also the only one from the flock that will let me pick him up without any fuss.
