I've picked up poop in a 5 acre paddock and bagged it all, lugged it up a hill to the front of the property to put it on the road to sell, BY MYSELF in about 4 hours. There were about 4 horses on the property and it hadn't been cleaned in 2 months
As everyone else has said, horses are just hard work. You gotta love 'em to do it.
If you think picking up poop for half an hour a day is too hard of a job, either get a ride-on mower or quad bike and get something to attach to the back so you can spread the manure, or, start paying for your lessons.
