I am concerned with my poor little dumpling, every now & then I find blood all over his legs & around his spurs, & sometimes he will pull those big feathers out of his legs & make them bleed too. (Being a total wuss that I am, I get horrified, rush him into the bathroom & doctor the wounds, put neosporin on them & bandage them, then kiss them) I am wondering why he does this. I know it hurts him. I checked all his towels, his stuffed duck, his basket & pillows & there is nothing I could find that would snag his feathers. When he absolutely wants to move he uses his wings for balance, not his useless llegs. What could be causing this?
