There have been a few confirmed cases of bird flu (in birds) in our county this year and the county has been marked as having an established presence of the disease. I have been wanting to set up an outdoor aviary or at least a cage for Wrangler where he can have some fresh air and sunshine. How do I protect against him contracting the disease? Are there any vaccines, precautions, sprays, etc? Is it contracted through mosquitos only or can one bird pass it to another in some manner (feces, feathers, etc) Suggestions/advice?
