Manna Pro Crushed Oyster Shell for Chickens, Calcium Supplement, 5 lb Bag

Manna Pro Crushed Oyster Shell is a premium calcium supplement formulated specifically for laying hens to support strong, healthy eggshell formation and overall skeletal strength. This natural source of calcium comes from heat-treated oyster shells, which are ground to an optimal size for slow, steady absorption by your poultry. Offering Manna Pro Crushed Oyster Shell self-fed allows hens to self-regulate their calcium intake based on individual needs, reducing the risk of soft or thin-shelled eggs and promoting peak laying performance. This supplement is an essential addition to the diet of backyard chickens, especially those on grain or layer feed, as it provides supplemental calcium not always delivered in standard diets. It also helps maintain strong bones and supports long-term health in laying flocks. With no artificial additives or preservatives, Manna Pro’s Crushed Oyster Shell is safe, effective, and trusted by poultry keepers who prioritize nutrition and egg quality. Choose Manna Pro for all your backyard chicken needs.
