Cherry Stone^® Poultry Grit is a clean, hard, angular grit to aid in digestion for poultry. Made of 100% crushed quartzite, this grit is even harder and sharper than granite which enables the gizzard to work faster and more efficiently. Cherry Stone grit won’t dissolve in the gizzard, upset the mineral balance of feed, or neutralize digestive juices so it does a more thorough job of digestion. Due to its unique rose color, Cherry Stone Grit is often used for hobby crafts, aquariums, flower pot drainage, grill liners, paver joint fill, aeration, and other decorative purposes. Our grit is available in 50# bags in four sizes to cater to every size bird and it comes in a pink-gray color which birds are attracted to: #1 (BOM #105237), #2 (BOM #105238), #3 (BOM #105239), and #4 (BOM #105240). Also available in 2,000 lb. bulk bags.
