I have six chickens and they are all fairly friendly, but this one red hen is like a little dog. She's around my feet whenever I go out and sits on the arm of my chair if Im out in the yard. Lately she's taken to staring in the back window into my office. Today the door was left open and she came bounding in, hopped up on my desk and made herself at home. Is this behaviour normal? She makes me laugh
