Starting this week, I'm formulating a ration for my birds. I can get whole grains, beans, peas and even soy bean meal much cheaper than chicken feed. I can also get alfalfa cubes to make alfalfa meal for fairly cheap, relative to chicken feed.
Since I finished butchering the Cornish Xs and my next batch doesn't come for a few weeks, I figure this is a good time to get started on trying my own ration.
I'd like to find a cheap supply of dried milk to make yogurt out of.
I'm going to grow chia, quinoa, clover and rye grass this fall, along with mustard greens, turnips and a few other garden veggies just for the chickens. Maybe some rape seed. I'll grow buckwheat, amaranth, sunflowers, corn and squash next summer. I'm also going to be looking for sales on Halloween pumpkins.
I'm also a member of a meat coop to feed my dogs RAW so I get some really good deals on sell-by day meats sometimes. The chickens will be getting some of that as sometimes I'll get things that my dogs don't like.
I really don't like paying premium dollar for a bag of feed which is really just a bag of stale  "by-products" when I can buy whole ingredients and make something fresher and better for less. My chickens also free range over the walkways of my garden. It's not a big area but I fertilize, seed and water it so that it's the best grazing that they can possibly have.
