Just so everyone is clear on this...I have six coops with six runs. All are different sizes. The largest run is 8' wide x 24' long. The smallest is 3' wide x 6' long. I spent $41.69 on 500lbs of play sand from Home Depot. It barely did my Sumatra & Crevecoeur pens. Frustrated, I made some phone calls & discovered the local sand/gravel place sells "truck loads" (your truck) for $17.50 It's a heavy concrete mix type sand with very little gravel in it. And it drains wonderfully!!! I went down and they first asked what kind of truck I had. I told him a Chevy and he smiled and asked what size? I told him a 2500HD and he said, OH that will work! And filled my truck. It didn't look like nearly enough sand but it did make the truck ride differently. I got home & had previously shoveled about 6" of dirt/poo out of each run and "prepped" them for sand, raking them smooth and leveling everything out. I did three smaller runs and then started on the larger run. I only got about 1/3 of the way down before I ran out of sand. I went down for another truck load, racing the sun as I was quickly running out of daylight! I got another load and the guy seemed impressed that I'd shoveled that much sand in a few hours, alone. Interested, I asked him how much (weight) that sand was. His reply was 2,600 pounds (per load)! So after shoveling 5,200lbs of sand into SIX runs yesterday--I can barely MOVE today! LOL Husband was impressed and replied that I must have "really wanted that done." LOL The runs look MUCH better already!
