## Description

Product description               Oyster Shell Grit 200g. ---- Oyster shell grit is used to provide poultry with enough calcium to produce strong bones and good egg shells. Modern poultry laying feeds usually contain sufficient calcium but there is no harm in providing some additional calcium in this way, particularly if poultry are being fed on household food or straight cereals. ----- This product is also suitable for controlling pH in wormeries and often used by organic gardeners, who sprinkle the grit around the base of plants as a barrier to slugs and snails. Can be fed from feeding houses, bird tables and on the ground.                  Ingredients               Oyster Shell               
                  P.when('A').execute(function(A) {
                      A.on('a:expander:toggle_description:toggle:collapse', function(data) {
                        window.scroll(0, data.expander.$expander[0].offsetTop-100);
                      });
                    });
                
                        Directions               Provide oyster shell grit for poultry to consume as a source of calcium for strong bones and egg shells, especially if they are not already receiving sufficient calcium from their regular feed. This can be done by sprinkling the grit on the ground, feeding houses, or bird tables.             See more

## Customer Reviews

### ⭐ Really rough, no good for my chickens and quails
*by A***R on 12 June 2023*

Really expensive for the little I got and no good due to the large size of the shells. You need to work this your self before you can give this to your poultry. No good.

### ⭐⭐⭐⭐⭐ Bought for my wormery
*by A***R on 18 January 2020*

I buy this for my wormery

### ⭐ do not buy
*by M***N on 18 June 2019*

I thought this product a real rip off and completely stupid, I bought it thinking it was a big bag full of grit but it was not just a handful Do not buy
