I have a Polish hen and she seemed fine last night. Came home from church today and she was on the ground with her head down. She seems to be having trouble holding her head up. She is 1 1/2 years old. Her poop was a little watery and it was yellowish brown...doesn't look too bad. I have her some electrolytes in water through a syringe. What else do I need to do? What is wrong with her? Any ideas?
