I agree with most of what has been said, but I do not ever recommend that a bird be placed in a kitchen, it is a very unsafe and unhealthy place for them to be. There are dangers from glasses or cups and other containers being left with water or other liquids in them that a bird could get stuck in and drown, This does not even count the times when there are pots and pans of scalding liquids or other things that the bird could land in or the various hot surfaces that could seriously burn your bird. It does not do them any good to breathe in all of the greases, oils and other fumes found in a kitchen. There are just so many hazards there and all it takes is just one mishap.
Parrots are flock animals who depend on their flocks for safety as well as a sense of well being and so they are very frightened when they lose their previous support even if it was bad and move to a new place especially when they are all alone and they have no idea as to what strange new predators may be lurking in hiding waiting for them as a snack and they have no ideas as to what your intentions are. It is a very scary and stressful time for them. Take your time and let them watch you while you go through your daily routines and talk and sing to them a lot from a distance until the bird begins to show interest in what you are doing and begins to move away from the back of the cage to watch you, then start dropping an occasional treat in their food dish and walk away so they can check it out.
