I buy an organic feed and that's all I feed my chickens, other than veggies and fruit that would otherwise go in my compost. But then I started reading here about people who give their chickens yogurt and fruit and oatmeal and I'm thinking WHOA! Should I be doing more? Isn't the point of a feed that it's all in one? Also, my 7 month old chickens aren't laying (never have) so I'm not feeding any grit - is that correct? I have some cochins and some other varieties, and I know the cochins are slow to mature. Thanks!
