I have a few questions about what to feed and when to feed my chickens. They have just recently been able to free range. I have been giving them some greens during the day, like lettuce, radish greens and cucumbers. If they are free range, do they need to be given this? I also have been feeding them scratch, but they will not eat the cracked corn. Should I continue feeding the scratch to them and when would be good to feed them the scratch? And because they are mostly free range all day, should their feeder and waterer stay in their run or should I move it outside of their run? They also are feed crumbles in the feeder. I am so confused on what to feed them and when? Please help.
