Coloured eggs into incubator

[Kiki]

I can't tell much about what causes an egg to quit but it does look like these made it far/almost to hatch day. I think humidity and ventilation are the only thing that is in your control that could cause them to quit late. The other things that cause them to quit this late would be parent stock nutrition and genetics.

Both of these have really good info in them:

One thing I notice is a lot of people spread the eggs out in the incubator.

I keep all of the eggs close together with thermometers and the humidity gauge as close to them as possible.

That way I can be sure the temp and humidity is the same (as close as possible) for all eggs.


I don't think there was much you could have done differently.

The eggs were in an egg turner until the 17th day. I kept the humidity around 70% most of this time with occasional dips when water ran low. Maintained humidity at 70%+ through hatch.

I am otherwise happy, the 8 that did hatch are thriving!

70% would definitely kill all eggs in my bator.
I have 100% hatch rates regularly but I mostly set my own bird's eggs which are fed well and have no disease.
I keep my humidity at 30-35% throughout and only raise it to 50ish when I see the first external pip.

I relied on my memory for the percentages (a mistake when one gets older) and only checked when I went into lockdown.

It obviously worked out ok for you. I'd try lowering the humidity a little for next time to see if it works out better.

A friend managed to get them all somewhat looking at the camera.
