Hi Lisa,
Sorry to hear about the problems you are having. One of our other members just got her 5 month old grey last week, and she is worried about him hurting himself as he learns to fly, so she has turned a spare room into a "fledging" room, padding it up with old duvets and cushions etc. Maybe you could do something similar so at least your grey wont get hurt as he finds his wings! Then he will hopefully become more confident!
Let us know how you come on.
Lyn
