Social Life

I've noticed that the animals have begun to sort themselves according to type. Yesterday morning I made it out to the pasture to move fence at 5:30 and caught them bedded down in separate groups: sheep, Jersey steers, and a group of Lowline Angus and Scottish Highland steers.

This morning I found the same groups each grazing their own section of the paddock.

I wonder what happens out there when I'm away and why the sudden shift in social dynamics.
