Hi Robin,
1/ I don't see the problem to mark queen after emergence, but to see
the results of the queens war
2/ There is no problem to dissect gently a queen cell along the height
(2 cuts from the top to the bottom, keep a piece of silk at the bottom
for closing) mark gently on the body and close the cell. Tight with
a small piece of parafilm while the bottom is free for emergence.
