I'm like Nrhareiner. Been using round bales for years. I also unroll it like toilet paper. I was finding dead snakes, implement parts and lots of dust. Then I found a new supplier and realized that I had forgotten what good hay looked like. I still unroll it by hand, rolling it back up into a smaller roll as I go, put it on a kids plastic toboggan, put a net over the whole thing and pull the toboggan out. I've had the same nets going for 6 years, no holes.
I also laced together 3 hockey nets for $60 and covered the whole round bale. It also takes my three a week or better to eat through a bale. I put it up on a plastic moulded skid (no nails) because if the bale is dry, it will literally suck the moisture up off the ground. I also put an old horse blanket over the bale, but under the net to keep it dry from above, as I also have no dry place to put it. I find the big bale offered does not regulate them like I'd hoped. They just sat there and ate, gained weight and pooped out the other end without moving. Doesn't encourage movement. 3 horses on a bale lasting a week is just about perfect in terms of rot setting in and using the nets saved me $400 last year, in what would have been waste. Here in Ontario, they cost me $29 each, delivered and loaded in my barn. When I realized that the tractor could do all the work for me, I bumpe a bigger door in my hayloft for it and never looked back! The big bale also worked like a charm last summer when I went away for a week and no horsey-type helpers to fill in. First bonafide vacation in 20 years and if it wasn't for the confidence that that large feeder provided, I never would have left.
