Good for Chickens, NOT for Quail
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!

My hens don’t like it
My hens were molting and needed more calcium. I am not sure if they like this. It looks like very small white gravel. I put it in a bowl and it doesn’t seem like they are eating it. I have taken to sprinkling it in the chickens run. The hens maybe setting it. I just think it’s not as chewable as they would like. It appears to be of good quality. My hens are just picky. They won’t even eat earthworms.
