I have a pullet (maybe full grown, but small) that came to my back yard from nowhere and will not leave. My cat and dog are ok with her being there; but she will often run up to them to see if they will move or not. I know that chickens are social animals; do you think she is trying to play with them, or is this a territory issue? She comes up to our patio window and waits for us to come outside or let the other animals out, and will occasionally follow my boyfriend around the yard - she truly seems to like being here and is trying to play... we're just not sure. Want to make sure she's happy. Thanks for any thoughts or advice!
