We are planning to make a 4x4 square that has 3' tall walls and is 1' off the ground (so we can cut our 8' redwood posts in half and so we can use a precut piece of plywood -- we are lazy!). We want to make a hipped roof out of 2x4s with a ?2"? overhang and then either sheath it with OSB (we got some foil covered stuff in the home depot scrap bin) and asphalt shingles or use old fencing to make a lapped roof (but then we have to figure out what to do with the seams at the corners). The 'walls' are just going to be open hardware cloth we think as we live in San Diego and it is extremely mild. How high should we put the roosts? and how far apart should they be? We could put one in the middle of the house at the top of the walls but because of the angle of the roof I'm not sure how many chickens would squeeze up there. Also I asked in another thread but I don't think I got an answer, can nest boxes be in the outside run or do they have to go in the coop? If they go in the coop does it subtract from the minimum floor space for each chicken?
