Not sure about cotton seed but soymeal and canola meal are very commonly included in poultry feeds as a protein source. In garden soil feather meal would be a slow release source of nitrogen. Feather is mostly composed of keratin, a protein, it could be fed to chickens. .
I bought a 50 lb bag of soybean meal at the feed store, It is 49% protein so I thought it would make an emergency food source for the dogs/chickens and me. The stuff was horrid, I tried it and hated it, the chickens didn't like it, and I didn't feel right about feeding any of it to my dogs.
I looked up whether it could be used as fertilizer since I didn't know what to do with the bag, turns out it has an n-p-k ratio of about 8-1-2 makes a great slow release fertilizer. Easy to apply and a little goes a long way!
