I have three pullets, roughly 16 weeks old, who are normally very quiet, only making the typical cluck/"model T horn" noise and the occasional squabble when one tries to steal food or sit on another's head. But in the last week all three of them have gotten REALLY LOUD! Not crowing, or screaming or anything... but their normal noises x10 on the noise scale and way more constant. In fact, one is "talking" non-stop in her very best outdoor voice. Does this mean anything or are they like my seven year old daughter and suddenly have realized louder equals more attention?
