best to pull a broken blood feather. it can reopen if he simply knocks it against something, and theyre really painful. they can also have that chance of getting infected if left in.
ive pulled over 50 blood feathers with tsuka and his wing problems. its easy and isnt as bad as it sounds. tsuka is also very prone to nightfrights.
trust me, its not as scary as it sounds. it will hurt, but it will hurt more if the quill is left in.
ive had some nasty feather issues with tsuka, it took him a year to learn how to fly...
after you pull it, he may have some pain in the wing, just keep an eye on him, make sure he is eating, even add a bit of honey to his water for energy. clean the area on his wing after to be sure its clean and he should be fine
for example, here's some of the things we've dealt with with tsuka's feathers... hes really good with it, he knows the drill. these abnormalities have been caused from follicle damage from him either breaking all his blood feathers or knocking them out, plus his past environmental factors too.
THIS is that thing thats been pulled out
he had an ingrown feather that died off and started to regrow... the new feather pushed the start of the feather cyst out of his wing. this was a LONG time ago... but trust me, i am no stranger to broken blood feathers or feather abnormalities
do you know what caused his nightfright? if you do, is it possible to prevent it from happening again? if not, what are you doing now to prevent them? ie, how do you cover his cage at night, do you leave a nightlight on, background noise such as a radio or tv on low?
