My wife and I are new to chickens. Our flock is doing great, except our Plymouth Rock. She’s definitely not growing like the other chickens. We do see her eat and drink a bunch and her feces/urine is normal. She just doesn’t move a lot. It looks as if she is constantly falling asleep. While the other chickens are out scratching and pecking, she’ll stay for a long while in one spot then maybe move to a new spot and stay there for a long while. Any help or suggestions would be appreciated!
