Can you post pictures of these things?
I do feed them a 'porridge' every morning, with Verm-x Poultry Zest and fine Oyster mixed into their mash.
Usually a layer type feed has enough calcium in it for laying birds so I don't think I would mix oyster shell into anything. You could just leave it in a dish for them to pick at it if needed.
I'm wondering what the porridge and Verm X things are.
