Manna Pro 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.

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.

Great grit for my chickens. They actually eat it.

My chickens love it, a must have!

Fair price and well packed. Just seems a bit large. And be a better mix of small and medium and large grit. Other than that, a decent product.

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!

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.

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