I have developed a wheat allergy and celiac disease and need to find a way to feed my birds that won't make me sick. All the commercial feeds I've been able to find either plainly say they contain wheat or they contain 'vegetable meals' or something similar that probably do. I've done my own grain mix before. I fed corn, wheat, barley, milo, millet, black oil sunflower seeds, oats, and in winter I added some layer pellets for extra protein when there aren't many bugs available. Now I need to eliminate the wheat and barley. I know I'm being difficult and need to consider the birds' needs as well as my own, but another consideration is that since I can't get organics where I live, I've been trying to limit or eliminate corn and soy as well because of the GMOs. My birds all free-range during the day on 21 acres of pasture, so they have access to plenty of bugs and grasses most of the year, but I know in the past they've needed extra help in the winter months, usually December - February. Currently I'm feeding a mix of corn, black oil sunflower, a birdseed mix I picked up at WalMart. I have chickens, guineas and a few ducks, and plan to get some turkeys in the spring, so a mix that would be sufficient for all would be ideal. Thanks for any direction or links I can use to figure out what to do next!
