She is 2 years old i came out to the coop and saw her eye like this i dont rrmeber it beoing nlike the yeasterday butnit was dark in the coop so I may have not noticed. Her eye is buffy swollen and kinda running with clear liquid. She is seperated from the flock at the moment i had just got done treating a respatory disease in 3 other flocl members (not her) but she was exposed to them before teatment. She didnt seem to have any symtoms of the respatory disease so after i was done with treatment i put her and another hen back in to the flock. I research it could it be a secondary infection or?? Ill try to answer any questions you have! Here are some pictures Her normal eye Her swollen eye.
