So is there anyone that uses just play sand?? I see that some have used sand from their kids sandbox. I have 2 old bags (haven't been opened) of play sand. My dad used to use them for weight in his little pickup, and my kids aren't playing in sand anymore. I was just thinking of dumping them into my 10x10 coop. I've had my chickens for 3+ years, so of course, theres no such thing as grass in there, just DIRT. They LOVE to take dust baths in the 5/8 minus gravel we have (I was even thinking of making them an area of that??), but I also need to get rid of these bags of sand!! Their coop doesn't have great drainage, and the rain is coming to the PNW here soon. Maybe that would help???
