Mornin' all.
Cindy, Duchess is right, hay can be a fire hazard but I rarely buy more than 10 bales at a time since I only use it when the weather is bad or a horse is sick or lame and needs to stay in. That's why I don't have a problem storing it at my barn. If my barn was all wood then I'm not sure what I would do. Only my stalls and tack room are wood.
Morning. Yeah, I just look at all these plans for ideas. It's kept in the barn here but it's mostly metal and all the stalls have outside gates plus 4 barn doors.
