I can accept a change in some aspect of the feed I'm using, but when the feed is larger, smells different, hydrates differently, has far more "dust" in the bag than usual, AND carries a tag with additional changes noted on it, I tend to think there is in fact, something different going on.
Greg Grimes mentioned splitting hairs in another, similar thread, and while I agree that it may happen here from time to time, I truly believe that there IS a change in my new feed.
At this point, my primary concern is the source of the protein used in the feed....has it changed any at all??
