I am thinking here about a rather good size, well built dog house we have, Without walking out back to measure it, I think it's 4 feet by 5 feet and a traditional "colonial" style peaked roof. I was thinking about something on the line of the "Chick-N-Barn" style that has been elevated and a square box run very much like "Dawn419's" set up, very close indeed to be honest. I am thinking about fitting a roof vent in that style to the roof on it now and adding a hinged roof to one side. I would add a nest box that jut's out from one side and rework the back wall for a clean out door. Given that, I am thinking on the line of four or five chickens. Does anyone have photos of these conversions that have been done along these lines. With the prices of stuff now a days, I hate to spend a ton of cash on the coop. PS, thanks to my buddy Chris with the dog house idea! And I will be calling you about some chicks sooner than I thought it looks!
