Hello. I am planning on moving horses from hay only to pasture boarding in a green grass field. It is winter but the grass is still lush and green and I don’t want to risk colic or founder. I know it is recommended to graze for 15-20 minutes at first and slowly increase grazing time each day but I have nowhere to put the horse that doesn’t have grass.
Would it be okay to put the horse in a round pen (~45 feet in diameter) for a week or two before turning him out to a 0.1 acre pasture or will the round pen still provide too much grass for the horse? Would mowing the round pen before the horse arrives make it such that the horse would not have too much grass?
Thanks!
