I will send the info to my grandson who has a home chicken flock. I don't know where he gets his feed, but there is a local Tractor Supply.
Fortunately, we have a local feed mill (yes, they mill from basic grains), and this has been owned by the same
family for more than a century. I would hope my grandson already gets his feed there.
That family's original mill, water wheel driven..was on the creek, about 400 yards from my house, and across
the road back then, was a cheese factory.
Both used the water of a creek, originating with small lake up the valley.
