I have a Red Rump grass Parrakeet with a large growth on the side of his face. Any suggestions of a food supplement that will help will be appreciated. We feed him Lafebers pellets, apples, carrots, and pasta and grit. But recently I have removed the grit to see if that helps. Vet says the bird will bleed out if an attempt is made to remove the growth. Actually my main inquiry is does anybody knows of some one who has non mutant red rump parrakeets.? No mutants, that shortens the life span and they are not nearly as pretty as the pure red rumps are.
