My male cockatiels wing bubbles?
A few years ago I accidentaly forgot to bring my male cockatiel inside with the cage. The next morning I found my male cockatiel with a bleeding wing and the white cage bars had a bit of blood. i cleaned it up with a moist soft napkin. Now about 2 years later my male is still very active but his wing has like bumps on it only 2 bumps though. I am using medicine for this cause but I'd like to know the cause of these bumps. Should i put more attention to this and take him to a veteranarian or just keep with the medicine?
