My poor 8-year old Welsummer has been unhealthy recently. The last week or so she's been spending a lot of time laying down in the yard. She's been doing this strange thing with her neck pretty regularly too, where she stretches it out and moves it in a circular motion. We've massaged her crop a few different times (and she's spit up). Please see the video below of the weird neck movement. Any advice or ideas about what might be causing this would be greatly appreciated. I know she's old, and it may be her time, but I want to do what I can to keep her healthy and comfortable if possible. Thank you!
