Sydney our 2 1/2 year old Black Australorp suddenly became ill a couple days ago. She was not eating or drinking and was moving very slow and crouching in her nest box. She also has really watery greenish stools. I'm not sure what is wrong. Any ideas? I dewormed her on the first and she is somewhat more active and she is now drinking. I added the electrolyte stuff to her water hoping it would perk her up but not really so far. She is still not eating. Help please
