I've been trying to figure out what I would like to feed. I would love a GMO & soy free Organic feed but so far Ive only found Organic or GMO free with the sometimes added soy free. For selling purposes I think I will stick with Organic feed. They both sell for about the same price around here. They all are at about 16% protein. I would like to add more. What can I feed them to bump up their protein while keeping them on the regular Organic layer feed I've been feeding them?
