My rescue cockatiel mutilates, she's been doing better but today I came home to her beak covered in blood. I took her to the vet right away, she's fine. She's never hurt herself this badly though, just little scabs here and there so I was more focused on her plucking/barbering. The vet recommended a cone in case she has another "freak out" while I'm not home. I don't know what caused this, she started stepping up and hanging out with me more, and she got a new toy recently that she's been so happy about. Anyways...I don't know anything about cones except they're fleece and I just ordered one. Do I need to train her to accept it like a harness or just put it on right away to protect her?
