Would horse manure work as well in a garden as cow or chicken? We have a neighbor with a horse (It's across the creek, so I never hear it myself, but another neighbor reports that it's still back there and she and her small son stop and feed it grass every so often when they're out on walks). I could ask to go muck out the area a bit and put some in a pile to age, perhaps. Any thoughts? This horse probably eats the native grasses and hay.
