Poultry Grit for Chickens, Ducks, and Game Birds – Crushed Granite Grit for Healthy Digestion – Supports Gizzard Function – Insoluble Grit for Mixed Flocks – 25 lb Bag

I've used this for the past 2 years for our chickens. The chickens seem to like it, and it works like grit should. I've had no issues with this brand. It's rocks, but chicken-bite-sized. Not sure what else to tell you. I have it on subscribe-and-save which makes it a bit cheaper. For 12 chickens getting a bag every 6 months is plenty. I've even had to skip an order when I let the chickens free-range and they weren't using as much grit. It definitely goes a long way.

I use this as a soil amendment and top dressing for my succulents-- a great economic option.

For those looking for grit like you see on British gardening shows, this is the nearest I've found. Good size to add to soil for drainage.

Works as expected. I use this for my succulent and cactus potting mix. I’ve bought more than once, so I recommend the seller. They pack it in a box and the bag has a plastic handle to carry, very convenient.

I use this crushed granite poultry grit not for chickens, but as an amendment in my cactus and succulent potting mix. Granite is a great addition—it helps with aeration while also supplying trace minerals and nutrients that succulents seem to appreciate. This grit runs on the smaller side (generally under ¼”), which isn’t my ideal size, but it compares well to large, sharp sand and works perfectly in my mixes. The granite has a pinkish-red tint that looks fine in the mix, though color comes down to personal preference. It does arrive a tiny bit dusty, but I would rinse before use anyway, so that’s not really an issue. I also really appreciate that this grit is much more affordable and readily available than horticultural crushed or decomposed granite, making it easy to source for regular use. One thing I like is that the granite adds weight to the pot, which helps stabilize top-heavy succulents. That said, I usually keep it to about 20% of my total soil mix to avoid making the medium too dense. My mix typically includes pumice, calcined clay, (sometimes zeolite), and coconut coir along with the granite. Overall, this poultry grit is a solid, reliable, and cost-effective source of crushed granite for plant growers. While I’d prefer slightly larger pieces, it integrates well into a succulent-friendly soil blend and performs as expected.

I use this stuff (Manna Pro Poultry Grit -- insoluble crushed granite) in potting mix for succulents and cacti. It's the best material I've found for creating air spaces and decreasing the length of time that the potting mix stays wet. It's clean enough that I don't bother rinsing or straining it, and it's coarser than coarse sand. It holds less water than perlite, coarse sand, or pumice. The pieces vary in size and are irregular in shape but tend to be tiny slabs and flakes. A typical piece is about 5/16" x 3/16" by 2/16". I no longer put coarse sand in potting mixes. I use this grit instead. I think it's better because it holds less water and creates larger air spaces, and it's a little less heavy than sand by volume. It's dull brown and uniform in color.

This Grit is a great value and a necessary component in maintaining your chickens health. It is the appropriate size for the chickens and comes clean and ready to use.

As a long-term chicken keeper who now has to keep my birds enclosed due to predators like foxes and minks, all their needs must be considered. Chickens require grit to digest food, and since they are no longer free-ranging, where they consume little pebbles, I have to provide grit for them. Every couple of weeks, I sprinkle a handful of this grit in their pens and they consume what they need. Good product!
