I have a camera in my chook house so I can keep an eye on what's going on. Often my chooks will come out from laying an egg, walk around the house and pick up either a feather or a piece of shavings, they carry it to the door and throw it over their shoulder before going out! Has anyone else seen their chooks doing this? It's like a person throwing salt over their shoulder for good luck! Does anyone know what this really means?
