We have our first batch of Red Broilers. They are 5 weeks old. I have been feeding them regular Chick Grower/Starter as we also had laying chicks at the same time. Obviously the laying chicks will stay on that feed until they are ready to lay, but what I'm having a hard time finding is when and what to switch them over to finisher or all flock feed. These are supposed to be slower growing than the Cornish X's and I'm hoping to let them free range in the next week or so until we butcher them. Anyone have any experience/suggestions?
