I don't always put alfalfa in the mix and my recipe changes depending on what's available. Peas are also high in protein and starch so I really like using them. The chickens like them but sometimes rebel. They like change occasionally, it seems. I know most feeds have soy for that reason but the human health detriment is too high from my point of view. I used to live in soy growing country and I know how heavily they are sprayed! AAAARRRRGGGG!!!
