Good for chickens and harden up egg shells
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.

Great Product!!!
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!!

Perfect calcium supplement
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.

chickens eating it
Package was open, thankfully the amazon package was not torn. It works for the chicken but they will eat almost anything.

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

Calcium for my girls and I always take care of the girls.
Great source of calcium for my ladies, no complains from them. Wish they could make it much smaller for young and small breeds
