Being new to the chicken world, the behavior of them make me kinda wonder what is going on. The most recent behavior that is baffling us is have saw dust in their pen right now, just freshened today. Now two of the three chicks will actually burrow in flap their wings and kick saw dust everywhere. Then the others will come along and peck at the one doing it. We were just curious on what this all meant. Any help would be great thanks guys!
