macaw cyst above vent
my female blue and gold has a cyst above her vent one inch by one and a quarter. She has laid eggs in the past. Her diet is fresh human grade fruits, nuts no peanuts, veggies and Roudybush. Occasionally egg and granola. She has receive 1 cc cavamox for ten days but the cyst has not receded. What could be the causes? Possible surgery?
