I have 18 bantam eggs in the hatcher--today is day 21. I candled them on the 18th day and they appeared fine--full and nice air pockets. These are shipped eggs. Last night I noticed that one looks like it has pipped, however, it has this oozy stuff around the pip. Is this egg going to explode? Should I remove it and mess up the rest of the eggs by opening the bator? What in the world happened?
