LOL the minute I get the rake out to rake up the pen, Barg BARG barg Barg!! Usually it's a Silky who starts it, and pretty soon the whole flock is going BARG BARG BARG!!!! Every time!! I've never beaten my chickens with the rake(or anything!) or even chased them with it, I rake up at least once a week, so it's not like this is some new thing...they are just weirdos!! I think it's funny, but strange.
