I've done "dry" hatching in a forced air incubator. Although it can be misleading when people read dry hatch. It doesn't necessarily mean not adding any water at all. It is just a hatching method running lower humidity throughout the initial stages of incubation and only raising it pretty high for "lockdown". For people in more humid climates this may mean they don't need to add any water during the first stages. But people in dryer climates will still likely need to add water. I ran mine between 25%-35%, and being in Texas I had to keep a dish of water in there to maintain that level. In most cases you want to be sure the humidity doesn't dip below 20%, even in a "dry" hatch.

I also dry hatch in a forced air incubator, as well as a still-air.
We are new to having chickens...adopted 11 Golden Comets from my inlaws after a hawk targeted their flock repeatedly. They were going away on a 3 momth trip and while the neighbors would most likely have been willing to feed them and check up on them, they wouldn't have been able to free range. So we took them....along with 11 more girls and a roo I adopted when our neighbors decided they wanted chickens as well. Just not in their yard LOL So we're 23 birds deep in chicken now. Some of the girls still shun our roo (Elliott's) advances so it seems our eggs are about 50% fertile with that percentage climbing by the week. He's a good roo...soo gentle...and he respects when they aren't having it. Anyway, I was scrambling eggs this past Saturday and noticed about half were fertile...those from our older girls...the Golden Comets. So I grabbed another egg I'd just collected that day and threw it in my shirt...not really thinking. But then I started to wonder if it was possible to incubate an egg so I googled it...and found this thread, among others. I was content carrying my little egg (affectionately named 'Tuck') around until I had another revelation. You can't introduce just 1 bird to a flock! I needed another at the very least. So 2 days later, in went another egg that grabbed my attention when I was on egg collecting duty for the day. The following day, I was apparently broody and added another. Clearly, this is before I was completely informed of the term 'Lockdown'...but I'll deal with that when the time comes. For now, I'm 6 days in with Tuck, 3 days in with Tooke, and 4 days in with my Tucca egg...which turns out to be a double yolker! So far, all three are fertilzed and Tuck is growing right on schedule; though his air sac remains small despite the humidity and I'm looking for advice as to what I can do in that respect. I read that if the sac is too large, there's too much humidity....to small and there's probablynot enough humidity. But it's been quite humid here and I throw a damp cottonball in with the eggs a couple times a day as well as drip a couple drops of water every now and again as I read that hens have been observed doing the same. As of yesterday, both Tooke and the Tucca yolks were dark and sort of move around but stay in one place as I turn the egg. It reminds me of a compass. I believe that's a good sign but I haven't seen any vessels yet. Hoping to confirm at least one of those eggs has a growing inhabitant(s) tonight. I know the odds are stacked against me but now that I started this little adventure, I can hardly stop knowing that Tuck is already a little life growing inside my shirt. I created a page on FB for my little eggs so if anyone wants to follow or if anyone has tried this before and would like to compare experiences and notes, I'd love any and all advice to increase my chances of this endeavor being successful. Thanks, all!
