Sorry
@Willawong Hill.
This hatch was the most disappointing we've ever had that I recall. Out of 20 eggs that were bouncy and moving at last candling around Day 16, only 8 chicks hatched. I have to blame equipment failure, not the incubator, per se, but the hygrometers, including the preset on the Genesis. I loathe digital hygrometers and could not find my little analog one, unfortunately. The discrepancy between the preset one on the incubator and the one I placed inside, the one that had been calibrated, became more and more wide as time went on so , in the end, I was not sure which was correct, though I tried to keep the actual RH between the two.
All chicks hatched cleanly, though, no excess fluid or open navels, which is doubly puzzling. Usually, open navels indicate humidity that is too high through a portion of the incubation, but that didn't happen. The last two chicks to hatch were, for lack of a better word, gooey, the fluid very viscous and making a coating that dried crusty. I gave the next to the last a little bath, the one you see in the middle of the picture. The last one to hatch is the one by the waterer on the right. That will be fine, of course, but they don't fluff out as quickly.
So, terrible hatch rate, but these seem strong so far. I hate not to have chicks for all three people who wanted them. I've never had it happen like this, less than 50% hatch. I can get hatching eggs and I am thinking of disinfecting and just doing this again immediately, find an analog hygro to use inside, or just go by the incubator instructions they give, water in one channel first 18 days, add water to the second channel the last 3, anyone ever actually do that? That was what my original HovaBator said to do, but I always used hygrometers.
