My Holderread Duck books says to mist every 24 hours during lockdown.  I use 100 degree water so the short humidity and temperature drop does not seem to be a big issue.  I've checked both and they are back up within 5 minutes.  Not enough time to effect the eggs.

Thank you, good info!
And thank you too Sundown Waterfowl
This is what I do with my calls, pekins, and mandarins.
Around day 4, I start cooling for around 10-15 min per day. I mist them with water during that cool down period. I do that up until I put them on lockdown. I either incubate them in my 
brinsea, which sits on a turning cradle or my 1588, and hand turn. I dont add any water to the incubator, just mist. I soak the eggs down when I mist them. With my 1588, I keep the vent either 1/2 open or all the way open. With the 
brinsea I keep it all the way open. When I mist, I just use room temp water. I also add some 
brinsea incubation disinfectant to the water with which I spray the eggs with.
Day 26 (for mandies), day 25 (for pekins) or day 23 (for calls), I move them to my 1602n or my other 1588 to hatch. I keep the humidity around 70-75% for the hatch, but the past few hatches it has been around 80% and they have all hatched just fine. I also hatch out all my eggs in cartons.
