Here in "Barter Country", I got these two Plymouth Rocks for sawing 10 logs into lumber for a friend. They were about 3 months old at the time, and unfortunately, one of them died just a few weeks later. Wouldn't come out of the coop all day, and stood in the corner. When I went to close everybody else up for the night, she was dead. Never knew what happened. The other Plymouth Rock has thrived in the new flock.
