My Barred Plymouth Rock Spurz feels terrible!! She is almost 4 years old and I went to pick her up of the ground and her keel bone felt extremely sharp. She has lost weight very fast, because we went to a show in October and she was fine! Is it possible that she caught something there? Please, any advise is awesome! She was my first chicken ever and I don't want to loose her. Her vent also has some fecal build up and is getting pale.
