I have one chicken (so far). A chicken truck rescue. Chicken Nuggets. I'm guessing her personality would be totally different from other chickens. We've had her since the first week in October. I guess she's about 12 wks old. I've heard that their organs get too big and not to feed them chicken feed. I've been giving her whole rolled oats and scraps. This past weekend, she started crowing! Any thoughts?
