Like Alexis, I have always fed chick starter until they are laying or getting ready to lay. I have read from multiple books that around 8 weeks it is good to switch to grower (different from layer or chick), but I have never bothered.
i feed my chicks medicated starter for 8 weeks that is mixed with game fowl for extra protein, then I mix the grower with it. then at 18 weeks i do layer feed...
You have great advice here! The only other thing we do is, say we bake more tater tots than we eat we give them to the chicks. I am a private pilot, so have people always bring me odd things to give the girls (becouse I gift them chickens at times), But I as others have said, soft. You will see.
