It may be my fault

I may have not read the label carefully or something but this grit is way too chunky. Like small pebble size . The previous grit I purchased was smaller and more

I may have not read the label carefully or something but this grit is way too chunky. Like small pebble size . The previous grit I purchased was smaller and more fine . I feel these are too big. They hardly worn touch it .

Great for Gardening

I use grit in flower pots and in the ground when planting wildflowers. It is great for soil drainage.

Love it!

My chickens love this grit. I have a newly established coop so the soil is still grassy. This helps a lot and they love it. I mix it with the scratch.

Exactly what it says!

This is a good all purpose grit that we offer free choice to our small backyard flock of chickens. I like that is has additional nutrients to support gut health as well. It is pretty funny to watch my gals get excited about a bowl of rocks, but they clearly enjoy it and often run over to check it out as soon as I refill it. Gotta make sure no one else gets the best bits first, right?! It's fairly uniform in size, low dust, and easy enough to lift the full bag since it's not too big (which is nice, as a not very buff, middle-aged lady). My only criticism is that I wish they were sized slightly smaller since I have a mixed flock with a few bantams and they seem to be much more picky, looking for the smallest pieces only. Still, it gives my gang what they need, and the price is fair for what you get, so we're happy with it overall.

Unfortunately not for Honey and Maple

This is a great idea. I have struggled with getting my chickens to eat grit. I have 2 extremely spoiled Barred Rock hens, and they are in general uninterested in grit. I offer oyster shell also and struggle to get them to ingest that as well. Full disclosure: my chickens live in a coop with a sand bottom. They are not free range. I had hoped that this grit supplement would stimulate them to eat grit. The grit is colorful and a perfect size for chickens; it's just that my little divas will not eat it. I think it is more a function of my chickens and not the supplement! I offered it mixed with their food in a feeder, in a grit cup on the side of their cage, and also broadcast over the floor of their cage with treats like dried insects. As far as I can tell, they have unfortunately rejected it and not eaten any. We have been trying it for about 2 weeks.

Healthier Chickens with Poultry Grit by Manna pro!

Since using Poultry Grit by Manna Pro, I have noticed our chickens are more energetic and have an overall healthier appearance. They have always been good layer’s, but I have noticed an increase lately. I have never added grit to their diet as I’ve used an “all in one” feed. They do have an area to roam and we give them time to roam the back yard. I think we will continue to use the Poultry Grit, since we have seen an improvement in their overall health. Our chickens are part of our family and with the price of eggs these days, we want to take really good care of them.

The rocks in this grit are pretty big, but my small Phoenix rooster doesn't seem to mind. Another review said that the person's bantams liked the grit and because I have bantam hens, I bought it. I don't know how those rocks are supposed to fit in their little beaks and get down their throats, but these hens eat a lot of things that don't look like they'll fit, so maybe they're okay.

I Hadn't used granite grit before, so I was interested to see how they would take to it. The product is nice and clean. Of course there is very light dust when pouring into the bowl. It rained the first night I put it out, so the next morning I went to pour the water out of the bowl. The water was all very clear. The chickens took right to it when I put it out. I will continue to use it.

I received Manna Pro Poultry Grit Supplement from Chewy and really like it. I mix it both with my chicken's normal food and the treats (girt, poutry snack mix and worms) and they eat it up. It's an easy way to get this supplement into my birds to ensure their health and wellness. Not sure if they can even taste a difference but they definitely eat it up. I will also say I love that Chewy has chicken supplies! It's so nice to have things delivered as I need it.
