Not if you do it quickly.
The first time I hatched anything I didn't have an incubator. I had a broody hatch her chicks and leave 2 eggs behind. I used a styrofoam minnow bucket, thermometer/hydrometer, and a heat lamp and made a quick hatcher. I dropped/smashed one of the eggs carrying it in (oops! felt so awful, I had to help it, but the chick ended up making it) but the other hatched fine. I used plastic wrap over part of the top to hold in some humidity and had a fan going near it, but not directly pointed at it.
I love that someone else had a makeshift incubator that worked!! That gives me new hope
