Has anybody ever done straw or hay bale gardening? We are converting my raised bed garden to the new duck/chicken pen (we have crazy grass here and while I was gone for work, it took over the garden beds and the paths, so going to start over). I've seen a bit about straw bale gardens and think we'll try that. But hay bales are 38923 times easier to find around here. Wondering if that would work as well.
