The part where you roll the ball to him and he goes P? I nearly died of adorable!
Now was he with you since he was a little chick? My older boy who I adopted from a family who couldn't take care of him just started mimicking.Haha, thank you =) He's always saying "P" throughout the day. If he says it once, you can say it back to him and then it just goes back and forth with "P"s.
