I have an egg that came in with a small crack. Ive tried the wax before and never had it develop. This one I put a small piece of paper towel covering the crack and rubbed some elmers glue on it. It dried and formed like a hard seal. I candled tonight, day 7, and darn if that little bugger isnt developing. What are the odds of it going full term? I know I have to watch out for it exploding, but so far, so good.
