The first thing to do if you see a feather bleedig is not to panic and I know this will be hard because our little feather friends only have so much blood to go around. Prefferable get the bird to a vet after putting on corn starch but not stiptic. Stiptic interfears with the re growth of the feather. All bird owners should have an emergency kit with a hemostat or needle nose pliers. If you must pull out the feather because of blook loss, pull it straight out and support the skin area some with your other hand. Give one slow methodical tug and pull. Bleedng should stop. I would still take bird to vet to make sure all parts of the feather came out.
