I have a female buff orpington in my little flock that I'm pretty sure isn't scared of anything. Even though I only bought them four days ago and I've been trying to move slowly (allow them to approach at their own pace) Betty (the BO) isn't even the slightest bit scared of me. Now she's trying to fly. My brooder is about four feet tall, four feet wide, and five and a half feet long and she's trying to fly. Hitting the walls, running around like a crazy bird, and attempting to fly out of the brooder every time the door is open. I don't want her to hurt herself but I'm not sure how to discourage this behavior. Is this normal? Should I be concerned? And is there anything I can do to make sure she isn't going to hurt herself?
