A little background: I have (15) bantam chickens and (20) pigeons, both of which are pets and a hobby. I am looking for ways to save money on feed and just be more efficient with what I put into them. I don't really want to venture into sprouting my own grains yet, though it sounds like a great idea- just not yet. I think I will start growing duckweed because I already have aquariums. I used to ferment the chickens mash when they were little, but it gets to be a pain int he winter in WI because the bucket has to be inside to keep it from freezing. But I want to start doing that again soon. I think initially I'll just try it with the pigeon grain, but eventually I think if like to mix some grains that would be good for both the chickens and the pigeons, and then supplement as need with layer mash and pigeon grain. Any suggestions? Or any wisdom on making sure the protein and fat percentage is right. For example I figure if I were to mix 75lbs of oats (12% protien) with 25lbs of sunflower seeds (26%) is equals about 15.5% protein. Is that correct? I figured that number by multiplying 12x3portions and adding 26 and then dividing back by 4. And I understand that fermenting increases protein by 12%, which would put the final protein content at 17.36%. Is all of that correct? Anyone have any insight into which grains are both the most nutritious and cost effective? Thanks!
