I have 12 hens and a rooster in a pen. They are all the same age (one year and five months.) I have several roosting rods. Two of the rods are on the same level/ height. I noticed the chickens will peck each other for position on the two heightest rods. There is more than enough rod for all the chickens to roost on one rod. The chickens do not sleep or roost on the same rod. Although the rooster is the dominant bird in the coop, he often cuddles with one of the hens. Should I add another "roosting rod to make it three rods at the same height? I have four older hens that I keep in a separate cage. when I add them to the main run, they run off all the younger ladies. I have decided to keep the "Golden Girls" in a separate coop. The Golden Girls get to free range and go into their coop at will. They are the original four hen that I have raised three years from baby chickens. I would like to have all my chickens in one large main coop/run. How do I get them to live peacefully together?
