I'm not an OTer, but I do use sand. I like it. Droppings dry out and can be scooped...backbreakingly scooped when I first put it in, now it waits til it gets stinky to get scooped. It is not maintance free. If the chickens are messy and spill water it mixes with the droppings and becomes cement like. You have to remove that hard part and replace the sand periodically....it does become stinky, just like a litter box. I have give thought to switching to shavings, thinking they might be easier.....but then I think about tracking the shavings into the house (cuz I am supposed to take off my shoes and yet, somehow I forget when I am just "running in for a minute"

) Sand scrapes off the bottom of my shoes quite completely taking the poo with it. I didn't have sand delivered, I bought "play sand" at Lowes. Some of it is better quallity than others. They both have their drawbacks and their strengths. The kind that is beach sand scoops easier, but it finer and does nothing for the chickens as far as grit is concerned. The courser sand (similiar to what you would mix with cement to make concrete) has little rocks that the chickens can use in their crop, but tends to clog my cat litter scoop more, so I throw more of it out.
I have had chickens for a little over a year, and have had to put in 3 additional bags of sand to replace that which I threw out with the poop. It does nothing for my compost pile. Shavings are better for that. (I use shavings in my nest boxes so I do have some mixed in with the poop in the compost pile) I figure I have spent about 30 bucks on sand in a year. How much would someone spend on shavings in a year? (Oh, and I have spent about $20 on shavings for the nest boxes in the same amount of time)
Hope that helps. (now I'll go back to just reading)
