I have had my Green Cheek Conure for almost two years now. Her feathers were pretty blackened when I got her but Iāve reduced so much of it after getting her from her original owner. My issue is that I need help on how to help get rid of the rest of the black marks in her feathers. Thereās a few green feathers with black in the tips and then thereās a little bit in her blue flight feathers. How can I help get rid of this? Please help.
