Whats the roof pitch on old time barns

Yeah, thats sbout what I got. Nope. Doubt if id need that many, and wouldnt have a source for that many anyhow. But, I might put it in loose. Been reading Haying with horses alot. Its an alternative. Ive got all the equipment. My bailer is old. Dont know if I can get it to tie right now or not. Will see pretty soon. If not, at 63, Dont think I want to go into hock for another one. Doubt if id run bailed hay another 10 yrs anyhow.
