Today I came home to find that Pippa, our beloved Speckled Sussex, is limping and sad. I'm not home on the weekends and just got here, but the people I live with say that she wasn't limping like this last night. We've examined her leg and there are no scratches or marks to indicate injury but of course she is hobbling and not quite her normal self. She is trying to keep up with everyone but not *quite* managing. She had to sit down a few times and is complaining in her sweet, musical chirp that we love so much. Is there anything I can do to help her? Please, please let me know.
