In my opinion , If you stomped around and cuss like you did when you hurt yourself every time you feed them , They would get use to it. Really, My neighbor and son drive the lawn tractors along the fence. My dogs are barking or the neighbors dogs. I am yelling to the dogs or husband. My chickens come running every time they see me because I feed them. I do just hang out with them and take a break and sit with them and enjoy them. This week I carry a stick and give a little wack to anybody who wants to peck at my body, excuse me I am not food. They still come to me. I feed them meal worms, stuff from the kitchen and the garden, wet feed and dry. It not because you were loud it is because you were different, that is what scared them. They will get over, it if you do.
