Ummm, Yes and NO! Yes I heard of it, but it's not a good recommended treatment unless your vet
has positively identified the respiratory issue. No because it's a water based product, meaning it's mixed
in with birds water. Most birds do not like the taste of the antibiotics in it, which in turn will condition your
bird to refuse it's water. Therefore depriving your bird of hydration. I'm not a big fan of antibiotics.
Those should be last resort and only when a chronic issue has been positively identified and not until then.
You do not want to give a bird stuff with antibiotics for no reason.
As a former vet, I would strongly caution you on the use of this product.
