Incubating goose eggs without misting and cooling

[yrtrnc]

I read in an article (https://www.thepoultrysite.com/articles/incubating-duck-and-goose-eggs) that misting and cooling may not be necessary.

This is what the article says " Another possible option – used by some hatcheries – is a single-stage incubation, where setter inlets, outlets and door are fully sealed for the first 14-17 days. Eggs must be clean, fresh and good quality, but not disinfected. As long the ventilation remains closed, humidity stays at 80 percent or higher, and the CO2 concentration can rise as high as 1 percent. No spraying is practised later on. Although not very common, this system leads to surprisingly good hatch results."

What are your thoughts on this. Has anyone tried this or not cooling and misting? What were the results?

Thanks

There are allot of things about CO2 although helpful in the first week and a half. It can also become a killer at the end of hatch.

Last year I held back on the cooling and misting and ended up with allot of small end pips and baby's being unable to pip even in the large end.

I spent allot of time reading this summer about fertility, healthy of embryo, I read mostly commercial study's done for production hatcheries.

This year I am misting hourly turning with 180 hand turning and cooling.

I did see the co2 thing from metzers farm though

This is a review of many of the study's. I red most of the attached studies

If you try it let us know how it goes
things to think about though how many of us can maintain 80 percent humidity without opening our incubator
