Once again, ad nauseum, he who knows little and is too cowardly to use
his name, is wrong. Gosh, why am I not surprised. My Grey is 10 years
old and still does it, alot. The fact is, mine did not start doing it
until he was over 2 years. Prior to that, I had heard of other's
describing it and I had never seen such a thing. He plays on his cage
floor with his toys and often scratches, yes, just like a chicken.
