I suppose if my humidity was under 40 I might add some water. I just never have had that happen in the 10 years I have been hatching (I hatch chicks and ducklings several times a year). I just watch the air cells. I also have tried weighing the eggs and graphing expected weight lose, but I...
I do not. I used too but it increased the humidity. Many of my eggs would make it to lockdown but not manage to hatch. A mother duck doesn’t add water.
Edit: I would if the air sacs looked too big. I did have one batch from different mothers where the air cells where different sizes. Some...
Ducks have extra thick egg shells. I do not see how someone can say it doesn’t work. I have tried both ways. I have had 100% hatches with ducklings hatched dry. I do watch the size of my air cells in case too much water is evaporating. In the fall, when my shells are thinner and the air is...
Yes, the egg shell is porous and water evaporates through it. In higher humidity, not as much water evaporates. This can lead to small airsacs and large ducklings which do not have enough room to zip to hatch. In extreme cases you get sticky chicks. In spring, egg shells tend to be thicker...
I meant, please don’t add water at all. Sorry, I didn’t read your post correctly. I would remove or completely cover the water. Your air sacs look small.
Please don’t. Too much humidity is way worse than too low. You end up with large ducklings which can’t hatch on their own. Mommy duck does not add water. I incubate dry until lockdown and have very high hatch rates. I would only add water if I was in a very dry climate.
