Review: Good for ducks - My ducks hate grit so this was ideal for mixing into their food. They had no problem eating it mixed in their food. The egg shells were hard and sturdy. It was a pretty good price too.
Review: Great for chickens, even picky chickens. - My chickens won't touch crushed oyster shells. This powered and gritty type works perfectly as I mix it into their layer feed. I don't have an exact measurement that I use. I just sort of spinkle it so it covers the top layer of feed and then use the scoop to mix it in a few times. Their egg shells have become much harder and I haven't had any broken eggs in the nesting boxes since starting to use this. The broken eggs were due to my "plus size" lovely ladies stepping on the eggs.
