I just built my chickens a new big coop and moved everyone in from three smaller coops. Now a young pullet just flogged me. I knocked her away and stared her down while telling her no and she was not queen of the coop I was. All the chickens backed away from me. What do I do to keep this behavior from getting out of hand? Is this part of their establishing a pecking order? And will it get worse when I add more hens to the six hens and one rooster already there.
