I read most of the threads. Got a lot of information. Giving oysters shells,free ranging ,this-that.
I read if excessive its harmful
My question is that what amout is harmfull?
And what happens if they eat excessive calcium?
So i have 6 chickens, all of them free range and lay eggs regularly.
My question is i do free rage them but do not supplement them with calcium or oyster shells but they lay all perfect eggs where do they get calcium from?
And can i continue this?
