In the Brooder
I have done it. I have not given my chicks extra calcuim and they all were good to go. So why can't I have input.So maybe leave the replies to people that have actually done it, studied their chickens behaver around the oyster shell from the day after they hatched.
Most chicks will try it out, but it only comes down to one or two pieces, and then they will ignore it until they do need it.
Some of my younger pullets will eat it, and I know that calcium is low in the soil here, so even very young chickens know what is good for them. Never have they comes to any harm from it.
