I believe they are happier this way, but they do sustain more scrapes, etc. from running around playing, charging through the trees and just being young and silly. A bonus is that I never have to muck out stalls!
Yikes - no kidding! I make a trip through my horse's paddock every week or so to turf out any big rocks, sharp stones, etc...in New England, the soil grows rocks like it grows weeds in other places.
Even with this weekly Rock Purge, my horse WILL find something pointy, somewhere, and then roll on it or lie down on it. He's constantly got scuffs and gouges from the dirt. It was worse when he was turned out with a paddock buddy, because 1) he loves to fight, and 2) see #1. When we were still trying to find another horse he could get along with, he was constantly scuffed and gouged from the dirt, and then always had little bite marks, or U-shaped shaved-off spots from getting too close to another horse's hoof. I just don't even bother taking the Yellow Ook (Tri-Care ointment) out of my grooming bucket.
Huey's definitely one of those horses that will find some kind of trouble to get into. The BO's mare is the kind that could injure herself in a rubber-padded stall. She rolled her leg into one of the tape-and-electric fences and got tangled up and bunged up her hock. Then, as soon as that was better, by golly she did it AGAIN. Did one of those four-leg little bucks, lost track of herself (she's a filly, going through a growth spurt, and getting a little tangled up), landed on her side, rolled, and stuck the same darned leg through a different fence, and bunged it up again.
That horse would find a way to injure herself on the bubble wrap. For her, we're thinking maybe just a padded bubble...
