Actually, my chickens have ESP.  I walk out the door and they all come running.  Could it be they recogize the red bucket that carries their feed?  Nah, they have ESP. 
		
		
	
	
I call CHICK CHICK CHICK CHICK CHICK, an so on, and they all come running.  Nothing is quite as funny as watching an Orpington or a Jersey Giant hauling their fluffy butts at (their) full speed from 100 yards away to get something from me.  Either watching the big, fluffy hen run from the front or back is sure to cause chuckles and giggles form just about anyone who sees it.
I have detected several vocalizations from my flock.  I also hear the blackbirds and starlings who have returned or are passing through and they will suddenly get very silent when a hawk swoops in.
I just heard my Silkies purring for the first time just this week.  My new Partridge hen was doing it, then I found that my 'dying to go broody' Black hen was doing it tonight.  The girl is getting broody over a wire bottom cage!
I have an EE girl who has THE loudest egg screech (no song, trust me) that I have ever heard, and when she starts in, the whole flock joins her.  Oh, but take that pile of eggs she tries hoarding to go broody and there is some serious butt chewing going on from her!  I call her Hen or Henry.  I couldn't tell which she was for the longest time until I saw her squat.  She lays a pinkish brown egg.  She may be leaving the premises soon for a new home at another farm nearby.  Maybe they can shut the loud beak up.
My two Sebrights are in the garage in a cage so as not to get walked all over my by JGs.  Whenever my dogs come around the corner of the garage, all hell breaks loose from them.  They are little tattle tales, ask Zeke, my Brown Standard Poodle (who has tasted fresh chicken tooooo many times).
I need to find that article, gritsar, I think it would be very interesting.  Do you know when it was printed?  I can hit my brother up for some old issues.
