Did the vet think the feeling of the air under the skin in your other birds was related to the excitement or adrenaline the bird experienced?
That might be why you see these symptoms in this roo. The roo in the movie clips appeared stressed, tired, and frightened. I would try to reassure him he is okay, even some Bach's Flower Rescue Remedy (which is okay in cats and dogs, 27% alcohol) to calm him down, pull pack his feathers so he can see, with some lap time to get his heart rate down.
