Humidity at the end of hatch?

[peawinkle]

Today is Day 25 in the incubation process. I've read different things about raising the humidity. Do I start raising it slowly from the 50-55% rh that it is now and have it at 75% by Thursday (day 28) or do I raise it only when one has externally pipped. What if only one has pipped but the other ones haven't, do I wait for all of them to externally pip?

You want it up before the external pip for sure. I raise mine as soon as I put them in lockdown and I have had excellent hatch rates. I take the term lockdown seriously!

Thanks for the info Kathryn. I added water to the trough in the bottom of the bator and it's now at 65%. I'm adding a little at a time through the vent holes in the top via a straw contraption (so I don't open the lid). I'm worried about adding too much water and the humidity going to high. At this rate I'm going to be up all night!!!

Is there a time frame from internal pip to external pip? Basically, when should I start worrying? LOL, who am I kidding... I've been worried from day one!
