I had a single bantam chick hatch and was declining fast so bought two 1 week old chicks from store and put with bantam. Within minutes bantam was eating and drinking and has been doing great since. Noticed from next day on the bantam trying to go under older chicks and when reaching in bin they will block and back bantam into corner as to protect it. Have added more chicks in as well and seems they are just being treated as mother hens. Is this an early sign of them actually being hens?
