This is my first time hatching chicks. I'm on day 21 in the hatching process. Several of them have pipped and are doing well, however one has rolled over and yellow fluid (I assume it yolk) that has leaked out of the bottom of the egg. The chick is not moving around anymore inside the egg like the rest of them are. My question is, do I roll the egg back over or leave it alone. I was also curious about the yolk or yellow fluid leaking out. Is that normal or what.
