Our sweet little chicks arrived yesterday and are happily sleeping, peeping, and pooping in their brooder. DH is out in the yard; the coop is done and now he is digging out the perimeter of the run to bury the hardware cloth to keep critters from getting to our chickens when they are big enough to move outside. I have read that sand in the run is THE way to keep things clean for the chickens. I am wondering is all sand created equal when it comes to chickens? The construction yard has a choice of washed and unwashed by the yard. Does it matter? Is there a type of sand to avoid? Please let us know! Thank you!
