i mix my own feed as well. I buy whole grains, non GMO from the feed store in 50# bags that store perfectly in 20gal steel garbage cans. It has cost me approx $60.00/yr for the grains I mix up batches as needed, each bach lasts about 10 days. The grains I use are 6 parts wheat, 3 parts oats, 2 parts sunflower seeds and 2 parts millet. I NEVER feed my chickens #2 field corn, it has NO nutritional value. I do, occasionally, treat them to an ear of sweet corn, and they love it, but it is only an occasional treat, like candy. I also add 1/2 part flax seed for omega 3s and 1/2 part split peas and/or field peas for added protien. I mix in some dried sage and thyme with the grains for their anti bacterial/viral/fungal properties and their resperatory health support and drizzle a spoonful of molasses into their daily ration for extra vitamins and minerals. I supplement with meal worms, crickets, fresh fruit and vegetables as well as scraps from the kitchen. I somethimes cook up some fish for them and I grow greens in the garden for them. I let them free range when I can watch, but after losing one hen to a coyote, I dont let them out of their pen unless I can watch them. I also add ACV, garlic, basil and oregeno to their water. I keep a compost pile in their pen so they have plenty of fun digging through that and I get excellent compost for my garden. They also have a sand pile to dust bath in and like to hang out under to coop when it's very hot, or raining. Right now I only have 2 hens and 1 rooster, SLWs They are beautiful, strong, healthy and no issues with parasites or runny poo, We're hoping to increase our flock this spring by having baby chicks, if not I'll be in search of a few SLW pullets.
