"I also keep a small dish with extra calcium in it for them to lick as they need more and they love it. For this, I do use cuttle fish bone all crushed up. What I do is to take a pocket knife and I shave it of onto a plate and then use my fingers and smash it a little more on the plate so as not to get any chunks, and it works fine and they really like it. "

Thank you very much , this is the info I was looking for and going to do the same thing.

Thanks again
