If you are planning to show your bird, it should never be clipped.
If you are not willing to do the work to train a parrot, then you may want to reconsider if getting a bird is right for you.
Ask yourself why you want a bird if you don’t want it to fly or don’t feel that your home is a safe environment. Consider that a different pet may be more appropriate.
Birds are very sensitive to stress, and it is possible that the bird may have a heart attack when forcibly restrained.
