Hi, I am just wondering what the best feed is for laying hens when it comes to a human health standpoint (Not necessarily egg production wise)? Currently I feed Layena, but am a little bit concerned about what's in it. I've been reading up on animal product claims from www.howitlived.com and it made me wonder what I'm feeding. For one, Purina claims the feed is "Animal protein and fat free" but that doesn't tell me that it's free of all animal products, such as gelatin coated vitamins. I'm also curious to know what other secrets may be hidden behind the feed tag. It just bugs me how many little ways companies can trick you. I just want to have the healthiest eggs possible. My chickens are free range all summer, but only free-run in the winter due to the climate (heavy snow). I have no choice but to use some sort of feed. Also, locally I only have access to a Co-op country store and Purina dealer for feeds.
