Please help me! We have a chicken that is 1.5 years old that we noticed that has been just sitting all day for two days now in different spots. She has never been broody so I don't think that's it. She usually follows the other chickens and runs when she sees us. But rather she is walking around slow alone and sits in different areas. She is molting and has lost neck and tail feathers. Do you think it's egg bound or a disease. What can and should I do immediately. DO NOT WANT HER TO DIE.
