Is there a more foolproof way to tell if your egg is going to make it than candling? My first experience incubating we had a hard time determining through the candling process and eggs that we thought might make it explained to us the phrase "last one in is a rotten egg"...more like last one out. I'd like to incubate again but our first time was rough because we had one born not fully developed. I realize candling wouldn't help in that case but it would definitely prevent the rotten egg smell
