I'm turning an old metal shed into a chicken coop. I've never had chickens before, but have wanted them for awhile. This shed started out as a dog kennel. It's about 10x10, with a 6' tall 10x10 chain link pen enclosure. The enclosure has a pitched roof frame that I can trap over for shelter from rain/sun. The whole thing is in a pretty shaded area of the yard, but I plan on insulating and ventilating. I've read a lot of the posts about turning a shed into a coop, metal shed dos and donts, etc.. Been a lot of help. What I need to know is.. Does each hen require her own nesting box? How much space (about) does each hen need? Average size laying hen. What is the optimum flooring? Currently just a dirt floor. I like the deep litter approach, but what, ideally, should a sub floor be made from? How long/tall should a roosting perch be? Does an elevated 2x4 work? I want to run electric out there for lighting mainly. Has anyone tried using an attic fan or bathroom fan to help force fresh air? What bedding works best? Easiest to deal with and keep clean? Sorry for the rapid fire of questions. I have a loose deadline of "sometime this spring" to get this done. I really want to have a clear idea of what I'm doing here. Thank you in advance!
