Thanks for your replies, she was throwinig her head back and flayling about with wings flapping etc, but not all the time she was also finsding it difficult to walk, kinda on her tippy toes !!
I got the vitamin suppliment and thought it can't do any harm ! so left her too it, she has been on one nest or another since mid Feb so was very thin and probably quite weak too, but she was now willing to get up and move about to eat/drink etc.
I left her in the capable hands of my mum while i went to Eygpt for a week
i have come back and she is fine not a flutter, flap or head roll in sight
whatever it was seems to have dissapearered xx
