update ..... welp, my gut tells me it ain't gonna happen.... while the membrane appears to have pulled back some, if i rotate the egg slightly i can see liquid moving, but NO mass movement and NO sound ... gonna give it another week of letting it sit there 'just in case' and then i'll do a neggcropsy ... still have my hopes, but they're SLIM ... if there's a point that anyone thinks i should intervene, let me know -- i don't mind putzing with it... and a SINCERE thank you to all for the advice and encouragemnent
