Over the last few weeks I've observed my 3 pullets lose their cute little peep, peep, and cheep, cheep sounds. First was Buffy (BO) who sounded like she was growling with a sore throat. Next, was Rocky (PBR) who joined the croaking crew. And today, between a few peeps, Rodie(RIR), started her voice change. Right now, at 13 weeks old they sound more like sick geese "honking" than chickens "Clucking"! Poor girls! By the way-when will they actually sound like full grown chickens?...or maybe I don't want to know.
