Hi all! I'm a first grade teacher in Alaska, and each spring I've hatched chickens with fairly good success. This year I was talked into incubating duck eggs instead by a family who had access to local fertilized duck eggs and wanted to increase their flock size. We're on day 20 of incubation, and I'm worried about a couple of things and hoping folks here have advice for me! We've candled the 41 eggs several times already, and have removed 4 that were not fertile or had early embryo death. We opened all those eggs after making the decision and were able to confirm that there was no duckling developing. So now we are fairly confident that we have 36 potentially viable ducklings only a week away from hatching. Squeeeee!! Our ambient room humidity is very, very low (about 14%) and the highest I've been able to get the humidity to go in the incubator, even with all the water troughs in the bottom filled daily, is 55%. We've been keeping data, and the temperature has stayed about 99.6 and the humidity 45-55% throughout the incubation. I've been so worried about getting and keeping the humidity high enough, but now the air pockets to not appear to be growing much. The opposite problem! When I compare it to the size on the chart I found on this website, the air pockets are the size they should be for a ten day egg. Unfortunately I didn't have a scale to weigh the eggs, so I don't have any other way to know how much moisture they've lost. We've been misting and cooling the eggs for 15 minutes once a day since day 10. Our incubator does have a fan, and I'm just worried if they are wet and gooey and that fan blows on them it might be very hard for them to get out of the eggs without drowning first. I would really, really hate to have such a tragic ending, especially with a very excited audience of six and seven year olds. Any advice or tips would be appreciated!
