I have a covert coop in a suburb and have been quietly keeping two hens in my privacy fenced backyard. They are good girls and go out when I let them and come back when I call them. I need three hens to supply the eggs I need for my family, which is all I desire from my pet chickens, and my MIL has a friend with a bunch of layers who wants to give me a particularly friendly RIR hen just so she can go to a pet home. What is the quietest way I can introduce her? I am considering simply turning the leaf blower on for a few hours. I think that even noisy hens are less noisy than other suburban noise.
