Treating blown eggs

[Steve Mills]

I found a small supply of pullet size eggs to use in my Malini Egg Bag routine.

I'm wondering how to strengthen/treat them.

A glue called Mad Podge (Diluted 50%) seems to be popular to coat the inside of the shell. It is also useable on the outside.

Does anyone have any advice?

Thanks.....

I've seen some experts simply use the blown shell, untreated. (Unless it was treated and they were just being quiet about that.)

I don't know about pullet eggs, but I have some blown normal eggs from the grocery that (amazing to calculate) are over 30 years old and they still look great, no extra coating needed.
