Hi all, today I have started to use cuttlebone on all of my DTs foods, I also use calcium +D3. I am going to use it like this, one day cuttlebone the next calcium +D3. I was reading online that you can put the cuttle bone whole into there tank and let the nibble on it when they want. It says the cuttle bone left whole serves two purposes, one it helps keep there beak in condition and two it helps with brain development (keeping them from being bored). Anyone have any insight on this? As the way I use it is I take my knife and lightly scrape the cuttlebone to create a fine powder over there food. I heard to much calcium is better then not enough cause they will just pass what isn't absorbed. Is this correct? Any insight on this would be cool.
