Hi all, This was covered awhile back but I got advice from the nutritionist at Purina. I have two month old chicks and 13 month old hens and put out both Start Grow and Layena mixed with Scratch. Purina nutritionist says that chicks younger than 18 weeks shouldn't have Layena due to high calcium content that will cause bone deformities. Older hens can eat it all but if they get a lot of Start Grow their egg laying will diminish. None of them really need scratch if they get one of the other two. My dilemma is that I only have one coop and confined yard and they pretty much eat whatever they want. Duh! When I build my permanent coop I'll divide it and the yard in two for both ages and feeds. Right now I'm struggling and enrolled in the School of Hard Knocks. Hope this helps somebody.
