Hi all! Just wanted to throw a word of caution out regarding builders sand that is not bagged. I love sand in my runs and aviary. One of the best things I have ever used. I just had a load delivered yesterday. I have bought it from this same builders supply store for several years. Today, while we we loading the wheelbarrow, my Granddaughters sharp little eyes found a roofing nail! I was stunned to say the least! We spread out the rest of the that load by hand and found another one. Now we will spend countless hours.... with magnets in the big pile of sand! Yay! what fun I will spread each grain by hand to avoid my ducks finding any more sharp metal objects to swallow! Speaking of magnets...I busted up some old speakers. The back side is a large magnet. I tied a long string to the speaker side. Now I can just walk along, without bending over, and pick up any dropped nails/screws/staples. Works great!
