So once again I am taking Bingo into my avian certified vet tomorrow.
My main concern is his breathing like it has been the last 4 winters.
Despite keeping humidity at about 45% and a slightly warmer house temp.
Also going to have his feet looked at (trim toenails and inspect the bottom of his feet).
I am going to strongly resist my vets insistence on checking for gram negative bacteria in his crop.
I don't see how it can be relevant to a respiratory issue.
Anyway here is a video I recorded and plan to show the vet at the time of appointment.
I think you will see my concern.
