I have 1.5 acres and the coop is 100 ft from the nearest neighbor. It is legal to have chickens in the county but the covenants of my area says no chickens. I have talked to my neighbors about getting some hens to make sure they are fine with it. I am also building the coop in the back of a shed so that it is not overly noticeable. I would say go for it if your neighbors are fine and accept that if they complain then you send the chickens to another home.
