I sat about 30 eggs in the incubator on Thursday (3 days ago) I decided to candle a couple tonight just to see if you could see anything. We have never hatched out of white eggs and my son and I were eager to see if we could get a better look at the process. I noticed that they have a very small air cell at the top of the egg. Is this normal for eggs this early in the process? Like I said we have never hatched out anything but our own brown eggs and you can never really get a good look at those. They were not shipped I actually got them from my uncle and I let them settle over night in the carton. Any ideas what is going on or is this completely normal. HELP!!!!
