Scratch and Peck Oyster Shell Supplement for Chickens and Ducks - High in Calcium, Made from Pure and Sustainably Sourced Flaked Oyster Shells - 4 lbs Bag

I run a small domestic duck rescue and have recently had a duck fall ill with heavy metal poisoning. The vet suspected oyster shells from a different well known brand. When I reached out to Scratch and Peck to find out where their oyster shells are sourced and if they are heavy metals tested they responded so quickly and put my mind at ease that they heavy metals test and their oysters are sourced from the PNW. I needed something safe for my girls to get calcium and they’ve always eaten oyster shells to help. I’m so glad I can feel comfortable giving my flock this brand and know they will be okay. Plus, they really prefer the flaked ones anyway.I only wish they did a much larger bag cause I go through so many.By the way, months later I am still awaiting a response from the big brand if they heavy metal test. (Hard eye roll)

We've tried other brands and our hens prefer this one. It's silvery flakes not white rocks like other brands. It does have kind of a strong odor (naturally) but that doesn't bother the hens, they eat it up. The shells on their eggs are perfect.

I love the texture of the shells and so do my chickens.

I’m a new chicken owner, I had gotten oyster shell as a calcium supplement but was recommended this product. I have this out in a dish for them to take when they want and they are going through this faster.

I like this brand because the feed for the chickens is great, however, as far as this product goes, the pieces of shell are a bit too big and my hen don’t care for it. Therefore, I am not giving it 5 stars.

Quality product that my chickens love. I saw improvement in my eggs immediately

Chickens love it. All the nutrients to have healthy happy hens!

I have this on auto ship, a little goes a long way. This is a good product.
