Our horses are out 24/7, even in winter. We give them free choice hay. We try to have them out on grass a few hours a day. We feed them square bales because we don't have anything to move round bales. Eventhough it would be cheaper to do round bales, square bales are better. Horse don't burry their heads as much into the hay and breathe the dust in. One of ours has heaves so we try to limit the dust. I put out 4 bales for 7 horses. They usually clean up most of it by the next day.
As for stables not feeding free choice, especially in the stalls, they do it so hay isn't wasted and cleaning stalls is less of a chore. It is better to have hay in front of them all the time but unles it is put in a feeder, it gets spread around, and gets pee and poop in it. Posted via Mobile Device
