you have more developed market in US. In Canada it is either in bulk for chickens at $12/55lb bag or it is a gourmet grocery item and than it is 10x times the price.For making beer, I see the horse feed as OK. For making bread, I would opt for the somewhat higher price since I don't like sand grit in my mouth eating food
Stuff is high priced when getting a small quantity from a Health Food Store.
Its not all they bad if getting food grade in larger quantity. It is higher than horse feed, but not out of reach.
I don't think they treat the grains with anything. (anything bad for people, is also bad for chickens) Only treatment of grains that I am aware of, are seed corn, Am not totally sure if it has something to do with corn not spoiling, or as a indication that it is a seed corn. Seed corn is quite pricey, and for obvious reasons.It is if the grains would be treated with some chemicals that would be not allowed for human consumption otherwise.
