Ok that's not to bad for three on a 1000 LB bale. Several years ago before feeder days we put out rounds 1000 lbs for three. Lasted 2 weeks but they had it tore up and four feet in all directions. But to my amazment they cleaned it up but they were also moving around more to eat it. So no four feet of poop built up.The farmer we bought the hay from said they were 1000 lbs but we took one to weigh it it was 1200 lbs. That's why they lasted two weeks.
