Southside Plants Oyster Shell Flour - High Calcium Supplement for Chickens, Amphibians, Reptiles, Mammals, Invertebrates & Birds - Harvest Delight Chicken Scratch | 1 lbs (1 lb)

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.

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.

Just used it! Best way to get calcium to my birds

I love this product. I mix it in my chickens food which means my chickens get the calcium they need and their egg shells are stronger.

We have been adding oyster shells for our chicken and since then our chickens stopped eating their own eggs and also the eggs themselves have became harder. The shells were very soft before that. They are defintly more affordable then other brands here but gets the job just as well. We just blend them up alittle because I do thing that it's alittle to chunky chunks for the chickens
