so im trying to get away from commercial feeds. i'm thinking, duck weed, dried comfrey, goats milk, black soldier fly larvae, oats, sunflower seeds, and amaranth. do you think they could eat amaranth? i mean, i could cook it if neccesary, but i really want to have a grain i grow at home just in case the whole world runs out of grains one day for some crazy reason. but i would mix it with the oats and sunflower seeds, also how much could i feed to them at once? basically is it poisinous? can i cook it to make it safe?
