I am an RN and comfortable with invasive procedures but I am not sure tube feeding a chicken sounds like a good idea for me lol. She does food fine it's the fluids. I use the dropped several times a day and it helps. She also did drink some juice I left out but not much. I'll keep the watered down catfood by her. It attracts more Flies so I think last have to move her into the garage. If I could get her solid food and fluids for a week I bet she would bounce back. I'll try the sling tomorrow and use towels. I am also going to get a cushion for her. Thank you for your replies and help!
I can't see anything else wrong with her either. She looks healthy from the outside now.
