Are soybeans toxic to chickens. I've read they have to be boiled, baked, somehow cooked to get toxins out...Is this true? I've had farmers tell me they scoop up excess soybeans and feed them to chickens, cows, pigs...whatever, and no adverse effects. My pa-in-law is convinced they will not hurt my chickens...but I want lots of info before I let them have anything. I've worked TOO hard putting together a flock for them to be wiped out by something like poisoning.
