I know that chickens do their best to keep their run solid, packed dirt. however, i have an overabundance of wandering jew in my flower beds and am wondering if I can throw it to the chickens (perhaps crossing my fingers that it will embed itself in the run ). I've seen it on the poisonous list somewhere but not on the poultry poisonous list. i have a solid green variety...smooth leaves, tiny little flowers in late summer. any ideas?
