So all pictures here are a different chicken? Her right foot looks like it has two bumps, it almost looks like bumble foot, I don't know why it would be on the top though. What does the bottom of her right foot look like?
So her crop was almost empty? The abdomen is below the vent in between the legs, I just want to make sure she doesn't have ascites. You may also want to try and give her some Nutri-Drench. Could you get a pic of the red spot near her vent?
