Pisces USA Fine Aragonite Calcium Chicken Feed, 5-lb bag
I have been searching for a calcium supplement for my quail for a long time. Normally what I find has big chunks of calcium for chickens and I would have to grind the big pieces in a coffee grinder. Not only was it tedious, it was loud and obnoxious. So I am very happy with this product! It is easy to spread and there is low powder affect.
This superfine calcium supplement has improved the strength of my Chickens' egg shells. They did not use as much of the oyster shell type supplement, and some of my birds were laying eggs with shells that were quite fragile, so I could tell who was not using oyster shell.
