Pink feathers

My older (19 yrs) Cockatiel's white wing feathers just turned pink. He seems to have more trouble with his footing too, and gets in the corner of his cage often. He still eats well. The pink is alarming & I think his feet feel warm. He has no new toys or pink anything.
I just noticed one of his toes is bleeding right beside the claw. Could he have hurt himself flailing about in the night? (If so, iI never heard him.) and there's a little pink around his beak.
