Our Rhode Island Red Rosie laid her first egg (the first of our pullets to lay one) on July 15th. After that, her voice changed from normal clucking to high-pitched clucking. Is this new sound because of motherly instincts, as if she hatched a clutch of chicks? She's still doing it today (and she's laid her second egg this morning). I'm not worried at all, but I'd just like to know what's happening.
