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 free-choice 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.

I offer these to my girls in a bin in their coop in case they need extra calcium.They know when they need it and will eat it when needed.Offers the appropriate amount of calcium unlike egg shells or other things I have tried.The price on Amazon is 2 dollars cheaper than any of the feed stores I have looked at.Will continue to order as needed.

This would be good for Chickens. However not so good for Quail. The crush size is too large for Quail. I have tried to reduce the crush size by blender, which did not work, and then bagging it and whacking it with a hammer MANY times, which also did not work. Holy cow, oyster shell is strong!

This is a good quality product, so you can make sure your chickens are getting enough calcium. So, if your chicken's shells are too thin or worse, always have a bowl of this available for your chickens to eat as needed.
