One egg loosing too much weight

[PaperChicken]

I have one egg that must be very porous. The other eggs are loosing the right weight and are on track. I'm afraid its going to loose too much weight and not be able to hatch. I figured on day 18 it will have lost 18.5% of its weight. If I adjust the humidity, the other eggs will loose more weight which I don't want.

Has anyone every put something on an egg to block some of the pores?

I've never hatched chickens, so I don't know. I've never heard of that, but i don't look that much at tutorials for egg hatching, so it may be common. I really don't know
I'm intrigued though.

I've never seen anything about it in the articles here. Smearing chap stick or something on the egg might work but it may rub in bacteria so it may not be a good ideal. I don't know.
