I have a not-even-a-year-old white leghorn rooster who has white discharge from the corner of his beak - when it dries it kinda looks like dried glue. He's been tested and they found "corynebacterium falsenii" and "klebsiella pneumoniae" and he's on his second round of anti-biotics because the previous one didn't work. He's soon done with the current antibiotics and he looks like he may be getting better, but does anyone have experience with this?
