Hello, this is the second hen I have had with about the same symptoms, the first one passed about a month ago. This one I noticed about 2 weeks ago with her head pulled in, and just thought she was cold. Now she is having watery smelly poop, it just shoots out of her. She sits on my deck all day with her head tucked in. I have seen her eating some grass late in the evening and early in the morning but thats it, the rest of the day she just sits, falling asleep. Please help. I dont know if this is contagious or just her getting old, shes 3. Thanks!
