Hey everyone, So a few weeks ago I had one of my 4 hens pass away of old age. She was the leader and took care of the other three. She had a best friend (they both are barred rocks) who is about 3 years old who hasn't been acting the same ever since. My two silkies seem fine but my super friendly and energetic barred rock seems really lethargic and isn't herself. I've also noticed her poops are bright green and super runny. She is still eating from what I see, I just don't know how to help her. She's the most friendly hen I've ever had. Any ideas?
