I'm a little confused about this because couple of people who have raised chickens for years have told me that if you let baby chicks have too much food, they will just keep eating until they die. The problem is that it has been a while since any of them raised chickens, so none of them remember exactly what age I can start safely giving the chickens a lot of feed for them to eat as they get hungry. So I need to know at what age I can do that. I'm pretty sure they are getting enough feed now, but it'll help me if I can put a gravity feeder in that will last for a while.
