Has anyone fed either/both of these and how did your chickens do? Mine are finishing a50/50 mix of Countryside Organics (love the idea, but the hens won't eat the powder) mixed with Purina start and grow non medicated. TSC was out of Nature's Best start/grow (of course! they never have what I want when I need it!), and so I grabbed a bag of the purina instead. They do like it, and are doing just fine, in fact poo doesn't stink... less than when they were on 100% CO. What are your thoughts?
