Novice backyard owner with small (5 hens) flock. Noticed the sexlink was moping- head down, both eyes are red and swollen, and she keeps them closed most often. This morning she was itching them and rubbing them on her wings and with her feet. She's not eating. I've tried to follow some posts and it seems like terramycin with a saline flush-along with isolation/quarantine is the best method? Any other suggestions? This is day 2 that I've noticed it and no other hens seem affected. Thanks.
