Frequently asked questions

Manna Pro Crushed Oyster Shell provides an essential source of calcium for laying hens, which is critical for the development of strong eggshells. Regular use can help improve eggshell quality, reduce breakages, and support the overall health of your poultry.

You should offer the crushed oyster shell in a separate feeder or container, allowing your laying hens to self-regulate and consume as needed. It's not meant to replace their primary feed but to be available as a supplement to their regular diet.

While specifically formulated for laying hens, the calcium supplement can also benefit other backyard poultry like ducks and quails that lay eggs. However, always ensure that the dietary requirements of any bird species are met when introducing new supplements.

The duration a 5 lb bag lasts depends on the number of chickens you have and their individual consumption rates. Typically, a small flock (5-10 hens) might go through a bag in about 2-3 months, but this can vary greatly. Monitor your flock's consumption and adjust as necessary.

  • Good for Chickens, NOT for Quail
Size: 5 Pound (Pack of 1) Style: Oyster Shell
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!
