I am an owner of 12 heritage chickens in rural NJ. Recently a neighbor of mine decided they too wanted chickens, so I helped them setup their coops and brooders. Our neighbors then went to Tractor & Supply and purchased 3 Cornish Rock Hens. My question is about wether or not they are exhibiting normal behavior. 1. They refuse to eat anything but their store bought food. You could throw a blueberry at their heads and it will not stop them eating the store food. 2. There is nothing wrong with their legs but they will still don't move that much and at times will poo then just sit down in it. 3. They are very flighty. Are they okay? They just seem much dumber than my birds.
