Product description

Manna Pro Poultry Grit with Probiotics is a 5 lb bag of insoluble, crushed granite formulated to support digestive performance for chickens, ducks, turkeys and gamefowl. The product is screened for an appropriate particle size and is intended for birds aged eight weeks and older.

The grit combines natural granite fragments for mechanical grinding in the gizzard with a probiotic complement aimed at supporting healthy gut flora and reducing digestive stress. There are no added medications or synthetic ingredients in the mix.

Use by offering the grit free-choice in a separate feeder or dish so birds can consume it as needed alongside their complete feed, whole grains and kitchen scraps. Regular access aids proper breakdown of fibrous material and can help with nutrient uptake and egg shell formation in laying hens.

Packaged to be easy to store and handle, this supplement is positioned as an everyday complement to a balanced feeding program for backyard and small-scale flocks.

Convenient smaller bags

I like having manageable bag sizes rather than giant sacks. These are easy to store and have lasted through a busy season.

Coop staple

Nice quality grit to leave in the coop. The birds use it as needed and it seems to be well-sized for them.
WWCO 5/5

Versatile product — poultry and plants

I’ve used this grit for digestion support in my chickens for years. I also sprinkle some on indoor plant soil to deter fungus gnats and it looks decorative while working well.
Codi Rhodes 5/5

Consistently reliable grit

This grit arrives intact and well sealed. My hens take to it and I don’t find debris mixed in like I have with other brands. A single bag lasts my flock quite a while.

Ducks approve it

My ducks prefer this over cheap alternatives — low dust, pleasant texture and sized well. They consume it readily and it’s been a repeat purchase.
