Oh, no, Lozzy! I missed your post. How is she? Any other symptoms? Tegan might have just gotten poked, pecked or scratched. Forget Marek’s and Coccidiosis on this one. If there are no respiratory symptoms, it could just be an injury. Sterile saline was the right move. I’d give it a little bit and you could always use an antibiotic ointment if it looks infected. Right now, I’d wait and see. Is the eye wet at all? If it swells around they eye, you might need to gently squeeze pus (which is solid in chickens) out, but I don’t see the need for that yet.
