I've read this forum for quite awhile and have learned alot from everyone here but today I have a question so decided to join. This is my first journey with a bator and today is day 21. I have 19 chicken eggs in and 14 are rocking and 5 have pipped. The first one pipped yesterday around 3pm with the others following within hours. They don't seem to be progressing very fast and I read it can take 24hours or longer. Should I adjust the heat any or leave it at 99? I'm so nervous they will dry to the shell before they make it out. Thanks in advance for your help everyone.
