Being the spouse of a chicken hoarder takes some getting used to. When this all started, I said I was OK with five hens - to meet our family egg requirements. She came home with eight. That was the status quo for almost a year.
Seven years later, I couldn't tell you how many chickens we have without some serious effort. I would say it's out of control, but my wife seems to have a handle on the situation. I don't ask questions any more, because I finally figured out chicken math.
