Well, for all we were going to give her an Easter-related name, given she rose from the dead on Easter Sunday, she seems to have become known as Wonky Sheep, as she still has a very slight head tilt! Not slowing her down with the slightest, she is back with the rest of the flock and doing well, and touch wood no further cases.
Thank you all so much for the advice and support, it was a real help.
