I've been doing my homework in prep for my birds next year. I came across this item called Proso in my McMurray catalog: http://www.mcmurrayhatchery.com/product/proso.html Proso is a grain (?) type of food you grown yourself for your birds. It gives little information other than it's easy to grow (does that mean invasive?) and its high protein. I was wondering if anyone here has experience with this product, good, bad? What exactly is it? Thanks for reading.
