I was wondering if it is best to pull broken tail feathers. I have been told that you should by a couple of people but I am not sure how to go about it if that is the case. Our cockatiel Elmo was always careless about tail feathers and has broken every single one and then its sibling would preen off the broken parts. So now they are all these pointy little stubs. I was told that broken feathers can irritate birds and promote plucking. If you have any advice I would appreciate it. I posted some pics in the photo section earlier if it would help to see.
