What's actually worked for me was to mix some elmers glue in a bit of water and use a watercolor paintbrush to apply it to the egg collar (all surfaces), and let it dry.  More coats can be added.  If you use enough water the coat won't be shiny, either, so it will look natural.  I did this with a couple collars I picked up in California a few years ago and they're still looking good.  Still fragile, so you need to be careful with them, but they're preserved.

Likewise - this would be an experiment.  Don't take your one and only
sample.

PEG is primary for wood, the principle might just hold up.  I'm
considering the concept
that the sample would always be in preservative, but would be stronger
to survive
looking at and storage.  This is a poly (plastic) replacement of the
water from within
the cells.  The poly enters the cells by osmosis and displaces the water.

My idea is the specimen would hold shape, not shrink or flatten. The
outer shell
would remain somewhat like itself being fortified.  Conserving color is
conceivable.

This might not work at all !!! <<<<<<

This PDF - shows how it works in wood - and I see a possible extension.

If you try it, keep us posted.  Museums likely have some on hand in a
far away department - wood Figures...
If someone has tried it - please report.
