I just did my day 18 candle of my eggs. Of the eggs I have full chicks in, I believe the air bubbles are to small. In some it seemed hard to see any. They are mostly brown eggs. A few lighter ones I could see a little bit of an air bubble. I hope my chicks don't drown. I thought maybe I would increase the humidity of my hatch this time around because last time it seemed of the five chicks that were ready to hatch, two died, due to getting stuck in their shell. Last hatch I was hatching between 30 to 40% humidity. This time I thought I would try 40 to 50%. It is currently sitting at 44%. I know I'm supposed to increase humidity 65 to 70%. But due to the air bubbles being small, should I allow my incubator to go dry for a couple days to day 20, then increase the humidity up to hatch level so they don't get stuck. Also, the eggs I left in the bator where black all the way through. Am I supposed to see an air bubble at all at this point? Am I just worried about nothing? Please, I need to know, any info will be great. I don't want these chicks to drown. I have 18 eggs ready to hatch. Thanks.
