You will need:           

1.  A pair of hemostats (preferable, as they grasp and lock on), or needle nose pliers
2.  Styptic powder, or cornstarch
3.  A clean towel for holding
4.  Spray bottle with room temperature water
5.  Two people make it easier

Capture your bird, and encircle it in the clean towel for control and examination purposes.  While one person holds the bird, a second person can lift the towel and examine the bird to locate the broken feather.  If there’s a great deal of blood, this can be difficult, so the person conducting the exam should then gently spray the bloodied area to get a clearer view of the feather shafts, and which one is bleeding.  Try to move the feathers as little as possible, as a broken blood feather is extremely painful to the bird.

Once the broken feather is removed, the pain will end, as you will be detaching the nerve from the follicle.  The bleeding will also end, although occasionally, particularly if the feather is a large flight, or tail, feather, a bit of residual bleeding will occur, but only briefly.

Removing the shaft:  As gently as is possible, place the hemostat or pliers opened tip right up against the skin line.  When you close the tool, and pinch the shaft, the pain will be intense for the bird, so make sure that:  a) the bird is securely held before beginning this procedure,
