I'm colorblind, so I'm not very good with colors, but the way to tell if it's an albino or not is by the color of the bill/eyes/legs. They'll all be pink. Your bird has some colored plumage on the chest, making it either a Leucistic (partial-albino) bird or one with plumage stains. Once again, you'll have to call the color of the bill/eyes/legs to determine whether this is a Leucistic or albino bird.
