I have a question. Pigpen, my rooster, has been having what I call "chicken farts". He will be doing whatever he may be doing at the time and just freeze and stare into space. I wave my hand in front of his beak "Yoo-Hoo Earth to Pigpen" and he continues to stare like he's been hypnotized. Then, all of a sudden he continues on his way like nothing happened. It's like pausing a movie. Is this normal or is there something wrong with him?
