Chickens only make several loud 'caw' singing noises at egg laying time and it doesn't last very long. Neighbors have one that does the noise around noon every day and that bothers no one (so much a nothing compared to the noise of a typical gardener mowing for 5 or more minutes). I did have a chicken in the past that with age/experience learned to lay the egg faster and made little noise at that special time. A city of relative says no chickens unless they are 100ft from someone else's home or business, so that screws people out of having their own in the typical housing tract. Some cities will allow a 'pet' maybe? To get around that law.
