I wasn't worrying too much about my air cells even though it has been really humid here in Portland (I am doing a totally dry hatch and humidity has been about 35 but went up to over 40) but when I looked at them yesterday before lockdown I freaked out a little, okay, quite a bit, because several of my 15 eggs air cells were really quite small. I read somewhere on here that they shrink during lockdown, but I wasn't sure if it was true. I thought about delaying lockdown because I didn't have any internal pips, but early peafowl can hatch at 26 days, so I went ahead and raised humidity to about 60- 65%. This morning I opened the bator because there are no external pips yet and stuck my flashlight on them and wow, in 24 hours all but one of the small air cells have gotten a fair amount bigger by about 1/8th to 1/4 inch. I was surprised and it made me feel super hopeful for a good hatch.
