Hate to break it to the people who love sand, but if you have mostly clay or subsoil (what modern builders leave behind!) you do not want to use sand. If you use sand, expect to always keep that area as a sand pit. When you move or you no longer keep chickens you or your new homeowners are going to be upset. Clay+sand+water= cement!!! Not the stuff you want a yard to consist of. I am assuming those of you who love the sand in a run don't have mostly clay soils. And one more bad thing about the sand, you don't want to use it in your garden. When you toss the poo to be composted in the garden that addition of sand will wreck your nice garden soil, again if you have mostly clay soil.
So, clay soil? I think you should say "NO" to sand! It maybe easy to maintain now...but it'll come back to haunt you.
