I tried Pinto beans and small red beans but got a poor germination rate.
Lentils work well.
Be careful, some beans contain toxins when sprouted, such as Kidney beans.
Rye grass works well for the birds.
A big bag of Oyster shell fragments is cheap and are pure calcium.
Sprout the Sunflowers and plant them and the nutrient levels will soar.
24-30% protein and the birds love them.
