29 year-old macaw doesn't grow flight feathers
I have a 29 year old blue and gold macaw. I've had him for about three years now. His left wing looks normal, but his right wing is completely void of flight feathers except for three or four at the tip of his wing. Needless to say he can't fly, nor have I ever witnessed him attempting it. I am unaware of the full details of his history. Could this be the result of some injury, or some procedure to permanently de-flight him? He's happy and healthy but I've always wondered why the flight feathers don't grow.
