Some of my hens are sneezing and have runny noses. Now one has a swollen eye and bloody stool. I have started them all on Cori in the water) tonight and the one with the swollen eye and bloody stool is not eating. She went for some bread so I gave her a small bit of bread with the Cori on the bread to get some medicine in her. I think it is Cocci from these symptoms. What else should I do, I think I am catching it early as she is still getting around Ok just slower.
