Impressive! Was this all hand labor? Scythes? Machines?
If the chickens are eating the eggs, sometimes that means they need mineral or protein supplements, although I've heard that once they start, it's a hard habit to break.
We started with the scythe, but we had such bad lodging (stalks bent over) that it did not work very well. We ended up using kamas, like these
for some of the grains, and plucked the others off with just our hands. VERY labor intensive to harvest, but that was largely due to our poor growing technique. If we could get a good, uniform stand that was all upright, it would have been pretty easy with the scythe. Next year - less horse manure (excess nitrogen can cause the plants to grow too fast, not have good root establishment, and be easily knocked over) and some way to turn off the wind...
As far as the threshing, we used some chain attached to a threaded rod, inside a five gallon bucket, and driven by a cordless drill. The attached photo shows most of the assembly - it just goes inside a five gallon bucket filled with grain heads.
Then for winnowing and cleaning we used some fans and some 1/4" hardware cloth. It takes a couple passes through each to get it mostly clean - we are still thinking we may have to build a de-huller if we want to get them perfect. They'll keep the way they are though, so that's for another day.
As far as the chickens go, I am supplementing free choice oyster shell, Redmond's trace mineral salt, and kelp, to no avail.
