It's slow solubility provides a steady calcium level, resulting in less bone breakage, improved feed conversion and healthier birds.\u003c\/p\u003e\n\u003cp\u003ePoultry grit should NOT be fed with feed, it should be left out separately for chickens to take in their own time. If free range, they will use less than birds kept in runs. This bag of grit should last 6 birds over a year. They will take small pieces to mash their food in their bodies and the oyster shell in the grit will be absorbed to aid shell production on the egg.\u003c\/p\u003e\n\u003cp\u003eGrit Size = Hen (4-7mm)\u003c\/p\u003e","brand":"Jondo","offers":[{"title":"4Kg","offer_id":56996541006156,"sku":"12674","price":3.4,"currency_code":"GBP","in_stock":true},{"title":"25Kg","offer_id":56996541038924,"sku":"12673","price":13.05,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1004\/6180\/5900\/files\/1685012062-62004300.jpg?v=1773682416","url":"https:\/\/www.burnhills.com\/products\/jondo-oyster-shell-grit-mix-no-2-4-7mm-for-hens","provider":"Burnhills","version":"1.0","type":"link"}
