I don't board my horses, but I do have 4 that I keep on a 2 acre dry lot all winter. I put about 80 tons of limestone screenings down a few years ago. It settles in sort of like a hard pan dirt that drains well and keeps the mud down.
Because of this I scrape the lot every week. I have a 4 wheeler with a front blade I use to scrape it. Then I pick up the piles of poo with a front-end loader on my tractor.
I keep a poo pile separate from the old hay pile. I didn't last year and it ended up having too much grass/hay seed in it. So far I have been able to use all the composted manure either on my garden, pasture (I have a manure spreader) or given it away to other family/friend gardeners.
I figure if I ever have some left overs I would run an ad on craigslist or just put a sign out front for anyone wanting free manure. Gardeners love the stuff so if your barn owner has the space I highly recommend starting a poo pile and either selling it or giving it away.
I want to add, my garden is about 99% composted horse poo. I always have a bumper crop of veggies.
