You are new here, but everyone is new at one time. Your posting title has all your questions. Nothing more in your actual post.,,,, Except the picture.
So let me answer by giving an opinion.
I see no problem with removing good eggs, to get to the cracked one. Then replacing the ones you took out, back in place.
My view of the jar in picture; It looks mighty small. Many peeps that water-glass eggs use a 3 gallon size container. Others use what is available to them, in other sizes as well.
I wanted to share this thread I link for you to inform yourself,, on water-glassing, and what others have done. There is a lot of reading there, but it has information on what worked well,,,,,, and what did not.
