I think he stated that the conventional i.e. non-organic stuff was at 17% protien, perhaps with the 5% increase in wheat and added barley? I don't know what the nutritional content of barley is.
He was also clear that every batch will have a different mix, if it is mixed at all. I don't know how often he runs a "batch" but said that some times it's 100% _____. Again just depends on what he's processing at the time. There are no bags, no labels, only a hand written ingredints list attached to the side of the hopper. The grain mixes are all bulk. I'm sure he figured out the mix ratio by knowing that this week he processed 1000lbs of wheat, 1000lbs of beans and 600lbs of corn - or whatever it equals out to.
It really sounds like it's a good source for some of the raw ingredients for a mix of your own.
Weather it sounds like a good deal to you or not... there are more opinions on what to feed your chicken than there is on what to feed your dog, so you have to decide that for yourself.
I'm just reporting what I found - Clean facilities, he charged me his previously stated price, and was forthcoming about what was in the mix at the time I purchased from him. I'll buy from him again, even if it's just for 'treats' to add to my other feed.
