I thought I read on here that Dumor is MADE by Purina?? Funny how people love Purina, but not Dumor. After using Purina for 4 years, I am finally going back to my local mill. They told me by phone that they still use animal protein, but I have to see it to believe it, because no one else around here does. Since going back to chickens almost 5 years ago after being without for 2 years, I have been feeding the vegetarian feed (all different brands) and have never been statisfied with it. The mill food will be about $1 cheaper than Purina. My problem with Purina is that it always smells like stale beer to me instead of grains.
