A few weeks ago OldGal and I went to pickup some feed for the girls. We, by default have always used 20% Layer Mash Krumbles. (Didn't even know there was another option ) Anyway, they were out of 20% and offered us 14%. We needed the feed so we went with it. Strangest thing; both the chickens and the ducks seem to be laying better on the 14% and it's a little bit cheaper. Anyone have an explanation?
