I have 8 chickens, 2 buff's, 2 Del's, 2 Rhode's and 2 Bared Rock's. The Delaware's are sooo loud and noisy. They just screech non-stop when they see you. I realize there chickens and chickens make noise but the Del's are annoying. Not sure I can do anything about it !!! There 22 weeks old and have just started laying the last week. Any Advice????
