I am hearing that flock raiser (from Purina) can be fed to chicks and hens alike as long as laying hens have access to oyster shells? I have 4 babies that are almost a month old now, and I want to let them all hang out with the older flock, with mama of course. I was doing this and all was well socially, but they kept eating the laying feed, and I was worried about their itty bitty kidneys. So I separated them with mama in a l smaller area of their run, and give them grower, and layers laying feed. I normally feed them organic feed, so that is my next question. Is there such thing as organic flock raiser? Maybe from another company? I know there is a solution other than putting feed up higher for the layers. The babies seem to find their way to it. Thanks.
