I have 6 chickens, 3 Golden Comet, 3 NHR and 1 RIR. The have plenty of grit, water, cracked corn and food available today. So I am changing out the water jug INSIDE the coop, they are all outside and all I keep hearing is a random "BAWK!" I watch and see 1 of my GC randomly pecking the other girls. Next thing I know, one of my NHR chases her and down she squats and gets a few pecks to the head. Is this establishing a pecking order or is it something else? Thank you!
