I agree, most vets wouldn't suggest natural or off-use treatments. I got lucky and found an integrative very who is also an avian vet.For that reason your vet probably cant approve or recommend. (I doubt many vets would suggest colloidal silver either.) The leg looks bad, but dont give up without trying a different treatment, since the doxy isnt working.
I also agree you should try different treatments if what you're doing isn't working. I wish your girl the best of recoveries.
