Well of course I have no idea about your particular place & grazing, but I have 2 horses kept on 4 acres, on a track averaging about 10' wide around the outside. The inside being electric tape & tread-ins, it's easy to move it to 'rotate' patches or lanes of grazing. I don't feed any hay. Over the drought we had, I found they ran out of grass on that after about 6 months, when I rested it completely for 4 months. But out of the drought now, they've been on it, on a track of various configurations, for the last year & there is WAY too much grass for them, so the moved areas off the basic track are small & far between.
As someone else said, rotating grazing is good management anyway, but I don't think locking them up at night will help. They are still free every day, to eat the choicest, generally already cropped short grass & leave the more ordinary, because it's longer & there's heaps to choose from.
