Well done and I'm glad Edmund is okay and you were able to resolve things.

It's my understanding that if a blood feather is broken or cracked and has been bleeding it always needs to be pulled because as Rebecca stated it is like a straw. Even if it clots it's too easy for it to open up again during preening or playing later and if you're not around to stop the bleeding it could lead to serious blood loss.
My Poi was in the middle of a molt when I adopted him and he was a skittish bird and broke quite a few primaries over the first several months. He was clipped at the time so there were no surrounding feathers to protect the new ones. Some would crack and some would break off completely but they would bleed and I had to pull them out. A few times he broke some in his travel cage just trying to get away from the vet and the vet pulled them as well.
I'm glad Edmund didn't bleed from the follicle; that makes it a lot easier. My Poi usually bled briefly from the follicle when the feather was removed but his were primaries and were larger. With pressure the bleeding from the follicle stops pretty quickly.
Jimmy hasn't broken a blood feather in years so I'm glad that's hopefully over with. I know it could still happen but now that he's flighted it's easier for new primaries to grow since they are protected by the other primaries, plus he's not so skittish anymore.
