When my mom was growing up in china, they had a few chickens. She said they were plain mutts, hatched their own chicks, and they'd sometimes be able to get eggs from them. She said they didn't lay much though vs the ones have now and always were "ugly." They fed them rice hulls and a "mash" made from what humans didn't eat. However, she also said, per clutch of chicks hatched, most would die. They were kept in wooden cages inside the home to be safe from preds and let out during the day.
