For those of you that try to feed pollen substitutes...
WHen I first tried to make my own patties I had a tough time finding brewer's yeast in quantity and price that I could afford. This past week I was shopping at a farm supply kind of a shop and came across some in the equine supply area, apparently it is a supplement for horses. I think it was about $8 for a medium to large peanut butter sized container.
Thanx for the info. Where did you find "expeller processed soybean flour"?
