Hi, im Josefin ive got two female parrotlets they are adult 7 year olds! The thing is that i have switched their diet a more then a half year ago. Becuase on a only seed diet, that cuased a long flaky beak, on one of them, and the other one got black feathers. I suspekt they didnt get all the vitamins. Now they are on a harrison bird food recomended from a vet that we talked to. And also gets fresh veggies. Things got better with my birds beak but she got black feathers too! So now they both have black feathers and i dont know if its something missing in their diet? They always preen and they are very happy, No sick bird behavior. But the only thing is their black feathers that makes me worried.
