In an effort to get away from adding water soluble vitamins in my dedicated 5 gal waterer, as it gums everything up and has to be dumped once a day I went in search of other options. Organic kelp meal was the answer based on my research, delivered via free-choice. The chickens enjoy it on its own and it's considerably more cost-effective. As I am a tinkerer I felt I could improve on just supplying them kelp meal and, for lack of better terminology, kill two birds with one stone. The final result has provided me with a supplement that not only chickens happily eat in a free-choice setting while not deviating from their regular feed but will provide them with increased protein and nutrients for molding and often unpleasant Ohio weather. Ingredients(I opted for all organic-not req'd): 1lb organic split peas 3oz organic kelp meal(horse feed supply website) 1/2c organic steel cut oats 1/2c organic scratch 1/4c organic meal worms 1tsp organic turmeric I put the split peas in the blender and pulsed them until they were the approximate size of regular feed crumbles. After that I added the ground peas and remaining ingredients in a large Tupperware, shook it up, and place in the chickens supplemental feeder.
