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.

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.

I love the convenience of ordering these oyster shells for my girls! I dump it right in with their food to keep the eggs hard and keep my chickens healthy! Thanks Amazon for making it so easy!!

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!
