Previous sand was wrong, this is the right sand! The previous post shows sand that is gray and looks like driveway small gravel. Not the kind I should have bought at Home Depot. It was tube sand. This sand here in the photo is the right sand.
It is construction sand at Home Depot in 60 lb. bags. A consolation for the leaks in the seams of the paper bags was the $3.49 price for one 60 lb. bag. Where I got the idea about sand is all from the great chicken website on the previous post. This sand is soft sand and must feel good on their feet.
