one of my 2 yo buff orpingtons seems to have a strange "shimmy" motion she is doing with her neck. kind of a back and forth like an egret eyeing a lizard... or maybe a hula dancer? this has just begun today. noticed it earlier but thought she was just working some food down, saw her doing it again just now. i haven't gotten a chance to examine her yet. will try to grab her when i close the girls up for the night. she has been going through a major moult, but otherwise should be healthy. wormed them a couple months ago, and i don't think it's gapeworm. any ideas? should i be worried that she's got something stuck in her throat?
