I wouldn't worry about dewaxing unless you're concerned that it can't pip through it. When I have cracked eggs, I typically use clear nail polish to seal the crack. I've had quite a few hatch on their own and there's no removing the nail polish lol
I got scared and quickly removed the wax. It is on the air cell part, so I was concerned it wouldn't be able to pip. Lol, maybe I didn't need to. ..
