Update:

today was last and third of the injections, and still got the calcium to give her twice a day; yesterday the egg looked liked it moved down, today it had moved back up into her body! Really frustrating:
Vet said give her the weekend and on Monday if there is no movement will have to look at two other opinions ..
a.) An operation; to remove it but this may leave internal damage,
b.) Try and "Milk" it out again, this can rupture the egg and again may lead to internal damage.
really am upset about this, and I don't want to loose her. But what's to stop this from happening again

? would really appreciate your guys experience and if which treatment was most effective for you!!
