## Description

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.

## Questions & Answers

**Q: I have 2 adult hens, how much should they be given per day or week?**
A: Put a bowl or dish with it out for them. Hens are very in tune with their body and know when they need calcium. Refill as often as needed.

**Q: Is this too large for vermi-composting.  Will worms eat it?**
A: If worms eat oyster shell and calcium they would eat this, it's good quality rock.

**Q: Hi can i feed baby chiks?**
A: You don't want to feed this to baby chicks. Only when they start laying eggs. Only feed medicated chick feed. You can add chick and grit later when there are about 8 weeks old. But do not mix the grit in with their feed. The oyster shell is to help with the calcium needed to create eggs. So do not give that until they are laying.

**Q: Where is this from USA ?**
A: I can’t find anywhere on the package a country of origin. MannaPro is from St. Lewis, but the bag says manufactured for MannaPro.
