ground shell

[johnbhoy]

i was wondering if its possible to use ground shell to build up calcium in hens
ie dry shells and grind them to a powder as i do this for my dogs and mix it through their meal

Do you mean egg shells, Johnbhoy? Apparently you can, but they have to be completely dried and well crushed otherwise there's a danger your hens could get a taste for them and start eating their own eggs.

They need to be baked first too to sterilize them. I save mine up and pop them in the oven when I've finished cooking. I use an old coffee grinder to grind them to a powder and mix it in with some mash or treats

yes eggshell sorry and thank you as this is what i meant as i feed this to the dogs completely ground down
