We live in an urban setting, with a yard of 6,000 sq ft, 4 hens. When they were younger they free ranged the whole yard. We finally confined them in the side yard so we could enjoy the garden ourselves without worrying about stepping or sitting on poo. They were let out to eat grass for half an hour when we get home early. Lately they tend to get so vocal, actually mostly just the RIR, that we think it might be too much for the neighborhood. They are well fed with whole grains and vegetables we barter from farmer's market ( with feed provided buffet style), there is an auto door built to the coop, and the side yard has dirt, trees and shrubs. I am thinking they are loud (not the egg sound) because they are confined and there is not a rooster. Is there any solution to this ? Should we build more vertical space for them? What kind of chicken toys could quiet them down?
