I would suggest looking into quail...the jumbo or Texas a&m variety mature form hatch in a couple mos. they are quiet and you can grow out quite a few of the little buggers in a relatively small area. The males are not very loud when they do start crow'n but because they tend to fight to the death over the girls you harvest them before the testosterone kicks in..lotta info about them on this site. And they are healthier than chicken, less fat!
