My local humidity is usually around 80% i run dry the first 18 days. Usually around 15% in incubator. And then put it up to 65% for hatch.Hi all, I'm about to start my final attempt and hatching some silkie eggs. Can someone please confirm if these levels of humidity and temp are correct.
Temp: 37.5°
Humidity 50%
Lock down 70%
On my last incubation I had the humidity at 60-65% and the one egg that did form got stuck and couldn't even get through to the air pocket when I opened it up it was very dry inside. Is there a post where I can see what the air cells should look like.Humidity should be adjusted to the ambient humidity at your location, not an arbitrary % based on what is commonly expressed in literature. A 35 to 40% RH for the first 18 days is usually adequate. I wouldn't go above 65% at lockdown, humidity above 70% at hatch time can cause the chicks to become "stuck", this is different from "shrink wrapped", which is caused by a lack of humidity. A stuck chick can not turn properly in the shell during the zipping phase of hatching. Sometimes it will pip then drown if the humidity is too high, the ambiotic fluids haven't been fully absorbed and can collect around the external pip and harden, causing suffocation.
As stated above, keep an eye on the air cells, they will tell you if your humidity is adequate or if you need to make adjustment to the humidity.

Ahh sorry didn't see that one, so not enough humidity the air pocket will be to big and to much to small? It looks like my local humidity is around 65%. This is my last try so really need to get this right.Number 2 ^
This is for a chocken egg.
If the air pocket turned dry, then obviously your humidity might of been too low. I never go lower than 68% during the lockdown period and my hatch rates are really good. Temp and humidity do affect hatching differently though with different people. Where I live, 35% humidity through days 1-18 would be way too low.On my last incubation I had the humidity at 60-65% and the one egg that did form got stuck and couldn't even get through to the air pocket when I opened it up it was very dry inside.

I havent had problems candling often. Just wash your hands before handling the eggs.Will candling to often harm them? Or is checking once a week OK?
