It's summer time, and my chickens are starting to molt, however, there is one that is about 3 years old that has lost some weight and feels light, she's been loosing muscle tone and her breast bone in more prominent. She eats, but I haven't seen her drink water, I hand syringe her water just to make sure she stays hydrated. Her stools been small and green and white. I recently dewormed her. I tried everything I can and all I have left is hope. Any recommendation to what I can do. Thank you.
