i have some chickens out in my coop that arent feeling very well. some of them have foamy stuff around the edge of there eyes, some are sneezing, some have a runny nose and yesterday my grandmother picked up one of my new chickens and clear fluid came from her mouth. im treating the chickens with sulmet but im not sure if thats the best thing to use. i really dont want to cull them so im wondering what they have and how could i cure it. thanks for the help. cole.
