Anyone have any thoughts on which you would choose...Dumor layer crumbles, Nutrena Naturewise layer crumbles, or Purina Layena crumbles? I was using feed from Rural King..Country Road layer crumbles. Chickens loved it and have done very well on it. Apparently they have changed the formula..color and texture are very different and chickens don't like near as much! Have a call in to manufacturer, waiting on a call back. Have used purina before when they were babies/growing up. Was curious about anyone's experience with these feeds/opinions etc as I look for a new feed. Bummed they changed it..everything else more expensive and not always in stock at the store. Thank you!
