Bird sweater will help prevent plucking and make your birdie look much better than a chicken ready to be boiled in the pot. It covers the back and torso of your bird where they often pluck. Notes: These sweaters also fit parrots other than Congo African Grey's that are the same size. This includes but does not limit it to Parrots, Eclectus Parrots, Pigeons, and Rose-breasted cockatoo.
