Just an added note- I got another email from the company. They have an organic poultry BASE- a pre-mix basically, that you just add to ground corn. A 60# bag of mix will make 1 TON of feed (mixed with corn, obviously) The mix is $56.80-a 50# bag of organic corn from them is just under $15-so, a ton of mixed feed will run $352.80-or approximately $17.64 per 50 pounds, which is not too bad at all I dont think! Now, if anyone can acquire (or grow their own) organic corn cheaper, one cna just order the base mix and really save quite a bit (for the person wondering about Michigan organic feed, an option like this might work well for you, you would only have to pay shipping on the bag of mix if you could get the corn near you) Anyway, just thought I woudl throw that info out there for anyone it might help. We are growing our own corn for this winter, so I know this will make a HUGE difference in our feed costs over the winter anyway!
Added note: She also said that as long as it is stored in a cool dry place, even an opened bag of mix should be good for several months time.
