I know what you mean about daily basis for those misters. The heat has been horrid here outside Eloy/Casa Grande. My biggest worry is respiratory infections because of all the extra water. Could you use a regular timer like an Orbit by just one day at a time only? I don't know and I bet there are a gazillion out there too for a search. You probably know a little ahead of time about the weather and could maybe program it for a few days, it can always be turned to off - just bouncing ideas. Good luck!
If all goes well, I should be looking at a July 17th hatch. Yes, my brooder is in the house too, and it sits right under my incubator. My young pretty Blue Australorp rooster has been busy with his 5 girls as even the splash hen isn't broody anymore and has gone back to normal.
