I could really use some last minute ideas! We are getting our carport sometime next week to turn into a new doe shelter/show barn for my daughter. We have 2" gravel down as the area is nearby the creek and drainage issues in wet months. So it's about 1' deep. We want to put something in over the gravel to pack it in - something we can sweep goat poop up without sweeping up the flooring too. Local farm store recommended Class I sand which is a mix of tiny pebbles and dust, but the problem is, we feel it will be easy to sweep up over time as the pebbles come loose. I'm not sure if crushed limestone is the same thing/different name. I've also been told dirty mix? We want something that will drain and not be awful for them to sleep on. Ideally I'd love to use shavings or straw on top. We didn't go with cement because we wanted something that would allow for drainage. Open to any ideas that can be done in a matter of a few days.
