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.

Le sirvió a mi gallina
Al principio no lo comía porque le costaba trabajo desbaratarlo, pero lo moli un poco y le gusta mucho. Esta poniendo buenos huevos

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.

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