About a week ago, one of our hens began to make gurgling sounds while breathing, and had the awful stink coming out of her nose. I isolated her and started her on water with ACV and garlic, and started VetRX in her water and down her throat and rubbed on her beak 3 times daily on Tuesday. Since then, she's perked up a good bit, the nasal stink has improved, but she feels gaunt and we've haven't seen her eat, even with mealworms and sunflower seeds in her food. She still has the gurgling sound. So, is it time to move to an antibiotic? From what I've read, it could be coryza or laryngotracheitis since it's not really responding to the treatments so far. So what should be my next course of treatment? Give it more time or move to an antibiotic?
