Leslie. .. You are in the right thread for the type of feed program you want. I am an active member of wapf and feed only non-gmo, home ground and fermented feed to my chickens during about 4 months each winter and they free range/rotationally graze with poultry electronetting being the remainder of the year. Can be done quite easily.
We don't have a lot of snow, but grass goes dormant in both summer and winter. We can't irrigate -- no water to spare in the irrigation pond, and there is a legal limit to how much "garden" water you can pull out of a domestic well.
Our biggest challenge is that we have too many birds to think they could all find enough forage in the area. I think we could do better with better forage, a lot better and we are working on that, but there is a limit to how many birds can thrive even in "green seasons" in this specific spot without balanced rations available to them at all times. I think we exceed that limit by a LOT of birds ...
Then there are turkeys, which are harder to feed at first. I could NOT get any non soy, non GMO turkey starter ... even sources I trust and who run GMO-free and organic mills said it isn't possible ... I have raised a few turkeys without proper starter, but the feed experts (organic and traditional) were unanimous that I use proper turkey starter *and* supplement it with chicken eggs as it is so essential turkeys get enough protein those first weeks.
We do grow wheat here, but it isn't organic as battling the weeds is an issue on this property. The feed experts I've spoken with (traditional and organic) are very skeptical about the validity of any products claiming to contain GMO-free corn or soy ... Corn can be avoided if you balance for it. But soy is harder to avoid for those higher-protein feeds.
I've really been doing a lot of looking into the situation lately. I do wish it were "easy" for everyone to have ideal conditions that eleminate the need for feed ....
What kind of grinder do you use? How many pounds of feed do you go through in a day? Do you really think it is necessary to grind the feed? If so, why? What is "poultry ejection being"?
LOL. Auto correct. Ejection being should be electro netting.
I got mine hammer mill from Premier One Sheep supply. I don't actually grind, I crack. My corn and field peas are whole and especially the peas are very hard. It ferments much quicker and easier if those two grains are cracked. So to make a balanced ration during confinement I use corn, peas, and oats. Those get fermented and then I add a mixture of powdery ingredients each feeding consisting of fish meal, limestone, alfalfa meal, and nutri-balancer. To balance that out further For chicks I add more fish meal and for adults I feed BSF (they are raised in the summer and frozen and fed over the winter - they are two high in calcium to feed to chicks). Keep in mind when balancing your ration that chickens need animal protein, not just any protein. Fish meal can be used for chicks because you don't have to worry about then having fishy eggs, but with laying hens you need to either cut back on it or eliminate it... This means you need another source of animal protein. We chose to raise BSF because it's ready and free.
So not using soy is very possible and so is avoiding gmo's... You just need to know where to look and get your ration balanced.
