I live at the Lake of the ozarks in missouri and want to homestead as much as possible while working 40 plus hours a week. Always wanted to have chickens for my own fresh organic eggs. I want to convert my metal shed into a coop , but still have reservations. Does the inside has to be insulated or covered with wood? The floor is covered with paverstone ,what do you recommend to use for covering those ? Thanks for all the input and help in advance.
