Need info on hatching duck eggs

[whitedove]

Will soon be receiving some cayuga and pekin eggs to try my hand at hatching.

This is our first attempt with ducks and I've come across varying info. What I've come across my husband thinks is too high and insisted I post and see what you all think. The search engine on here isn't so helpful.....so I apologize for repeating.

So, here's what I've found -

Days 1-25
99.5 degrees with 86% humidity

Days 26 - hatch
98.5 degrees with 94% humidity

Is this at all accurate? The humidity seems extremely high, but I've come across several people that swear by it. Any help/opinions/suggestions would be greatly appreciated.

That may be a bit on the high side but not by much. Ducks need really high humidity to hatch.

Yeah, humidity issues have been my biggest problem. It doesn't help that I am in a semi-arid area, but watch carefully during the hatch to make sure the membrane doesn't shrink wrap them.

keep in mind that those are wet bulb readings....they translate roughly into 55% before and then 65%+ at lockdown. ROUGHLY on a digital reader...

Did not know this. Thank you.

I do know that Metzer farms recommends wet bulb readings as more accurate but I am using a digital until I can find an old style thermometer as I can't get them around here because the mercury is now illegal.
