The video, http://www.youtube.com/watch?v=XDCk0DaNwiQ&feature=results_video&playnext=1&list=PL28AFB6F1D7079B62 Observation of our chickens, when a chicken walks the head is kept motionless and then moves quickly to a new position, repeating over and over again as the chicken moves forward. Interesting to watch, there must be a reason? So keeping the head motionless is best why? Is it a survival thing? Do chicken eyes move in their sockets? Thanks for any help!
