We ended up with 5 roosters out of a "mix"of 9. Now, we need to decide which rooster to keep. We have one that's so aggressive, if you turn your back on them, they will try to attack you (but if you pick it up, it will let you, being very agreeable with it), and some others that have only attacked on rare occasion, and two that run away when we try to corral them back in the coop, but have never attacked. I'm leaning more toward the most kid friendly, which would be one buff or a barred rock. Any specific behaviors that are better qualities?
