I have chickens, 7 adult hens and just bought 8 more chicks. I eat 3 eggs every morning, and use eggs for other stuff for cooking. They also have a "tunnel" that allows them to eat weeds in between the plant rows in the garden. Very efficient for weeding and fertilizing the garden, and you can see a noticeable difference in color between the fresh eggs and the store bought $16/dozen or whatever they are up to now. Since mine are "free range" or in the chicken tunnel they really don't eat much grain. I live in a neighborhood and they really don't make any noise. The key is not having roosters, and finding quiet calm breeds.
