I've recently been questioning what I feed my silkies. I normally feed laying feed and then I'll add some things like a scratch or treat mix, oyster shells, protine treats, diatomaceous earth, chick feed, and whatever fruits or veggies. But I've recently seen a lot of people talk about how they feed game bird feed, feather fixer, and black oil sunflower seeds and ect... I also heard that too much calcium from oyster shells is bad for my Roo? And that the diatomaceous earth is bad for their respiratory? I was wondering if I should switch to game bird feed and adjust what I add to it? Any advice or info would be appreciated.
