My cockatiel which I just bought today has been bleeding under the feather above his leg. It keeps running around left and right. My cockatiel seems to be stress. It is pretty young not sure about the exact age. It's been quiet the entire day but now it keeps chirping. I keep him in a metal cage and there are two wooden perches. At first, when I saw the blood he hasn't started bleeding but now he seems to be bleeding out. He was trimmed this morning by the pet shop owner. I am a new parrot owner. It plucks its wing and bites it.
