Manna Pro Crushed Oyster Shell Calcium Supplement For Laying Chickens, Poultry Treat, 5 lbs

Very good product. Good for your chickens 🐔

Great value, much less expensive than local stores. Chickens and ducks need this to assist with digestion so great for their health.

Great for the chickens, my egg shells were very thin and after feeding these and few weeks late I noticed the eggs were harder to crack.

We order this monthly for our laying hens & ducks & have never had a bad experience with it. The particles sizes are easy for birds to ingest & their eggshells are very robust. We definitely recommend.

This would be good for Chickens. However not so good for Quail. The crush size is too large for Quail. I have tried to reduce the crush size by blender, which did not work, and then bagging it and whacking it with a hammer MANY times, which also did not work. Holy cow, oyster shell is strong!

We just got chickens 3 weeks ago and hadn't gotten one egg. 2 days after mixing this in the feed me got an egg!!! Idk if this was the ONLY reason.. but got the price, it's worth a try!!

I offer these to my girls in a bin in their coop in case they need extra calcium.They know when they need it and will eat it when needed.Offers the appropriate amount of calcium unlike egg shells or other things I have tried.The price on Amazon is 2 dollars cheaper than any of the feed stores I have looked at.Will continue to order as needed.

My chickens love this
