I have a flock of all different ages oldest 5 months next week and some as young as 12 weeks my older ones are at age of being able starting layers feed but the rest are not how do I go about feeding them also I have 2 roosters in the mix I need something safe for them as well. I have read that roosters can’t have layers feed and they are all in the same enclosure. Also get limited time to free range in the evenings for a couple hours.
