Hi, I have a hen that is very sick. She is weak, has diarria and her comb is purple instead of red. She has dropped a ton of weight (couldn't tell thru all the fluffy feathers, but there's nothing left of her under that). I just brought her in the house and she's in a dog crate in my bathroom. Feeding her cocketel mix and trying to get her to drink water. I have some vitamin drops that I have for my dove, and it says they are for all birds, so I'm going to put some in her water.
What else can I do? She's about 6 yrs old, so I suppose it could just be her time, but she is my favorite hen from the very first chicks I ever had. Can anybody help Lucy?
