I'm so glad to see this thread! We moved in early Sep, and now TS is closer to us than the SS we used to go to (it's still the closest one) I was wondering if was my imagination or what! Glad to see others have had the same experience w/ Purina vs SS. I need to switch back! Way too much dust in the Purina, and I buy pellets!!! Plus I definitely notice my chickens don't like it as much as they liked the SS store brand! I think my chicken's egg shells are harder on the Purina, but they aren't laying as often as they did on the SS. I thought it was light, but I added a light to my coop, and I'm still barely getting any eggs! My bantams, who are super foragers, are laying way better than my big girls, and my bantams are separated and have no light in their coop!
Oh, and another complaint w/ the Purina? The chick crumbles are almost too big for day old bantams!!! What is up with that? They're huge! SS chick crumbles are a much more manageable size, and despite being ground more finely, I don't think they have any more dust than the Purina does.
