Can you feed those things? As others above have said, yes, with reservations.
Is it a sustainable diet?
NO!
Next up, what we really need from you is a LOCATION. Any home grown solution is going to be very much location dependent. We are also going to need to know how much space you have, how many chickens you plan to have, what your expectations of your chickens are, and whether or no you have any heavy equipment you plan to use to feed said chickens.
I did mention "
NO!"?
Not to be a downer, but the more I read about chicken nutrition, the less inclined I am to make a home-brew feed. Take away my ability to source ingredients via the internet, and its simply not possible*. In the last six months, I've seen three decent home-brew feeds. One is from Justin Rhodes. If you don't know who that is, and you plan to homestead, go do a Google search. His feed uses Fish meal. No fish meal? His feed is terrible. The second feed that was any good, I helped craft for a fellow BYCer in Ethiopia. It took most of a week/ten days, I had to build a calculator to figure it out, and an off the shelf solution would still be cheaper and better (if any was available). The third home brew solution I've seen worth a damn was this week.

@spaceylocust posted it in a
VERY informative Thread @Lauravonsmurf is assembling, which you should definitely read in full - it has links to older posts and lots of resources we've assembled. Spacey's feed requires alfalfa meal (that's harvested, heated, dried, not green off your field), fish meal (like J RHodes'), flax seed, hard wheat, kelp (!) - have an ocean nearby?, lentils, oats, and winter peas - that's a lot of crops to try and produce on your own, in bulk, and store for later use.
Now, can you bend your feed curve some? Sure -
I'm doing it with no tools whatsoever. I also happen to have one of the most tolerant climates in the nation. Are my birds surviving on it, nay, thriving on it? You judge -
culling pics.
I'm also working on a flock, specifically,
to thrive in these conditions. But keep in mind, I also feed hundreds of pounds of commercial feed each month, there are plenty of chickens out there that lay larger eggs, more frequently, that grow bigger, and grow faster, at better feed efficiencies. There is no "perfect" bird. At this point, I would argue that there are no great "dual purpose" birds, though there are some that are very good to exceptional. I'm hopeful, in a few more years, to have a bird that qualifies as "very good"
for my conditions. Just be aware that the things that make a great free ranger aren't the same things that make a great meat bird, or a great layer.
We can help you in your quest, but its a hard row to hoe, and will likely require some experimentation on your part to find what works best for you and your particular circumstances.
