5.0 out of 5 stars 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.Variation: Size: 5 Pound (Pack of 1)Style: Oyster Shell

5.0 out of 5 stars 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.Variation: Size: 5 Pound (Pack of 1)Style: Oyster Shell
