It is not bad to humans or animals, we use it in our home and it is just fine. We use it on our couches, dogs, outline of chicken coop, and more.Please stick with what the vet has suggested as treatment. The follow up is just 2 days away.
DE does not treat an active infestation it MIGHT help keep bugs away but is also a very fine powder that is easily airborne and very irritating to the lungs of many animals....humans included.
Your roo is already struggling so adding irritated lungs from a powder can throw the vet off the track of what is really ailing him.
