They had no problem eating it mixed in their food. The egg shells were hard and sturdy. It was a pretty good price too. ### ⭐⭐⭐⭐⭐ Good value and worked! *by P***T on August 27, 2025* Milled very fine. I am using this for button quail and they like the small size. Just have to make sure the opening to the oyster shell flour is small so they don't use it as a dust bath. Works great for button quail. ## Frequently Bought Together - Southside Plants Oyster Shell Flour - High Calcium Supplement for Chickens, Amphibians, Reptiles, Mammals, Invertebrates & Birds - Harvest Delight Chicken Scratch | 1 lbs (1 lb) - Pecking Order Oyster Shell - Calcium Supplement to Support Laying Hens and Strong Egg Shell Development (5 LB) - Manna Pro Omega Egg Maker, Chicken Feed Supplement for Laying Hens, Poultry Food with Omega-3 Fatty Acids, Digestion Support with Fortified Vitamins & Minerals, 5 lbs --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hr/products/409012504-southside-plants-oyster-shell-flour-high-calcium-supplement-for-chickens](https://www.desertcart.hr/products/409012504-southside-plants-oyster-shell-flour-high-calcium-supplement-for-chickens) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-07-14*
