I never expected flock dynamics to be so important to my hens. It seems that the "flock" is elevated over the "individual" even though my hens are all different breeds and colors. They are also developing at different rates.
It's cute when one chick stops pecking around long enough to look up and realize she's too far from the flock. If she can see them, she always speeds over to join the group. You'll see it happen 3 times in this video:
It kinda makes me wish that humans were a little more "flock oriented".
