I'm on day 14 of my very first hatch in my brand new Brinsea Eco 20. I candled on day 8 and 14. The air cell has grown by 1/8 - 1/4 inch, some eggs more than others. It is not as big as pictured in Hatching 101 article. My humidity has been in the 30%-45% range. It briefly pops up to 50% when I first refill the one well, and I don't refill until it gets down to 30% or so. I've caught it once or twice below 20%. So the average should be in the range of 35%. I have not salt tested the hygrometer, but two hygrometers agreed within 1%. Do I need to drop humidity until day 18- or do you think my air cell will be ok? Since this is my first hatch, I don't want to tinker overly much- since I have no experience- but am really unsure whether to make a change at this point. Thanks for your input!
