Help! I have a sick barred rock hen. She has green and yellow runny poo and She won't drink or eat anything. She has no energy and sleeps all day. She is also panting a lot. I keep her inside where it is cool but if she's not inside, she is outside with a fan on her. At night she sleeps on the floor and not with the rest of the flock perched on the bars. She has lost a lot of weight. Her crown is yellowish instead of red now. I don't know what to do! I'm so worried!
