Not easy but its that or you have to find it when you need it like now.Maybe. I only have a tiny hay store, everything has to get wrapped and that's expensive etc. They still waste a lot of hay in ring feeders compared with haylage
Where do you stop with buildings etc . They're Galloways
"Bay of hay" can mean anything from a bay of hay to a field of standing hay to a stack of haylage, whatever I think backup is a good idea
