Have you offered any other feeds? Your chickens could have some other issue than the feed. I feed Kalmbach and my chickens really love it. They prefer it to the Purina I recently changed from. The Kalmbach feed smells good==does yours have an off smell?Okay folks, another thing. I received this bag on 1/31/23 & didn't open until 2/12/23; with the mill date being 1/3/23 do you consider it old? I realize there could be more to it than old feed, but was always under the presumption that within 60 days of mill date is acceptable. My only choices are the local feed store (Purina only option) & Chewy (several brands to choose from, but only familiar with Kalmbach). I'll need to order something as eggs & soaked grains/seeds are not a long term option and of course they free range so have plenty of green stuff.
