Everyone lays down at some point back there, I found Bay laying down right smack in the middle yesterday and they usually have shavings or hay in their manes in the morning like they've been down. Lately when it's been mucky out, they're spending a lot of time inside during the day too. They've not had that luxury before. And they aren't messing it too bad, we've been mucking it out every-other day. They're peeing a lot in the outer lean-to, which is impossible to clean, it's a matted mess out there. So I wish they weren't doing that.
Why IS it that horses seem to want to do their business in the very place we don't want them to?! I had all that nice gravel put down in front of the barn door so it wouldn't be so mucky when I went down there to feed, and where do you think that every flippin one of them had decided to pee and poop? Right there in the door on the gravel. They'll come in from the pasture and poop there! I can get a wheelbarrow-full of horse crap off it it every day, and heaven help me if it's bad weather and I can't get to it for a few days. They'll completely cover the gravel up. It makes me crazy!
