Very Very Solid Choice
Gets the job DONE. It is healthy for my girls, it doesn't alter their taste, it has great texture, it has zero odor, and is super easy to use. However, if you free range your flock, then you do not need this, as they will find there own calcium sources and most feeds already have it in them.

Oyster Shell for Horticulture Soil
Absolutely Amazing! I am not using this for livestock, I am using it for horticulture and plants. This is 100% perfect for Cacti and Succulents soil mixtures. Great drainage, perfect.

Pieces are too large
The chicks are to large for consumption and hard to grind down

Works well for Ethel and Myrtle!
I can tell when the hens are using this product! (No I didn't ask them.) The egg shells are much thicker and they seem a little healthier.

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.
