Ask your vet if they will sell you Baytril. It's probably not approved for use in poultry in AU, but pretty sure it's used in cats, dogs, cattle, and swine.I don't think that Baytril is available in my country. A different antibiotic that a different vet prescribed for this hen late last year was called Clavulox. I do have some Aquari-Cycline (tetracycline disruptor) pills on hand, though; should I try using those?[/QUOT
