Need advice -oxine for respiratory issue

[amanda1]

I have posted several times here about my 9 month old hen who is having difficulty breathing. She has been head shaking for a few months, and about a month ago I realized she has labored breathing. I've treated for worms, she's had antibiotics and after a vet visit she is getting a drop of anti fungal in her nostril once a day. I have seen no improvement.

I have been researching oxine treatments but the information is limited. I'm thinking of nebulizing her like the article on shagbark bantams. I have no electric in my coop and my husband will not allow chickens in the house.

I am wondering if anyone has suggestions for treatment. How often should I treat her? How long for each treatment? I could probably take her to my moms, and enclose her in a crate for treatment, but I know being separated from the flock would be stressful. Do you think if I treated her one hour a day, in a covered dog crate it would help? I am desperate to help her recover. She has been sick for a while and she has never laid an egg because of it. I am not ready to give up on her and it seems I have used up any other options for treatment.

Any advice on oxine treatment and personal experiences is appreciated!
