Works good, I still have one chicken that has been having soft shelled eggs for a few months. Still no change, the chickens are still eating up the one egg from the one chicken that’s been laying thin shelled eggs. I increased feed with more protein, calcium and feeding black soldier fly larvae dried. Also the roostys daily for an over month. I ordered some from amazon the gold dust one, and one of the chili mix before I ordered a six pack at a discount directly from your website.
