OK, as I am reading this list of ingredients to DH, the ever-practical-to-the-point-of-no-fun farmer, (12 years my senior so we tend to be on a different page about several things!) he scoffs and says "who does that? all we ever fed the chickens when I was growing up was the same thing we fed the cows and pigs - ground corn and oats - and they were just fine. You're not buying all that crap just to feed chickens." .... So, my questions is, are all those things really necessary, or can I take that original recipe and use only, say, half of the ingredients? I dont know where to get quinoa or amaranth at a reasonable price. The grain elevators that HAD heard of those grains told me that they could get it to me by the ton and not very cheap... Can I use a base of our home grown cow feed, which really is just rough ground corn and oats, and add a few things like wheat or lentils, sunflowers, millet, and some grit and call it good? I can get everything but the lentils free on a regular basis, so if that is an acceptable mix DH would give me a lot less grief. I dont want to malnourish my birds though, so any pointers would be really appreciated!!! Thanks so much!
