Yep, it's proved once again. My chickens increase egg production significantly when on Layena layer pellets. http://poultry.purinamills.com/OURPRODUCTS/Products/Layena/default.aspx I don't know what is different in this feed, and I'm really not thrilled because I want to feed my birds organic feed (I sell the eggs in my health food store), but we've just gone from 1-3 eggs/day with 11 hens to 6/day with 10 hens, immediately after a hawk attack and two snowstorms (where they don't want to come out). (And no, it's not that they were laying outside - they are fenced in and I check everywhere for eggs.) Does anyone know of an organic feed that is composed the same way Layena's is?
