One of our hens has had one watery eye for a while and I thought nothing of it when I first realized, this was about 3-4 weeks ago. Originally I just thought it was something caught in her eyelid and it would go away by it self. When I went outside today to feed the flock I picked her up and realized the side with the watery eye was still watery and she had a swollen cheek (where the red part is, not sure what its cold). I've been searching for a while and I can only find some threads about sinusitis. I thought it may be a possibility but its just odd that only one side is affected. Should I be worried? If its contagious, etc. Would appreciate your thoughts and can get a picture if needed.
