I lost power due to an ice storm last year. Do you have a cooler? Do you have a woodstove or propane grill?
I put my eggs in a cooler with a couple of jars of hot water and covered them with a towel inside the cooler and a towel over the cooler with a thermometer inside overnight. I was able to heat water on the wood stove and kept checking the temp in the cooler. I was able to keep the eggs warm enough that I had a decent hatch out. Remember-hens allow a cooling off period each day when they get off the nest to eat and relieve themselves. If you keep the temp at least 95-98 for a few hours or overnight, you'll probably be OK. Try not to get below that or too hot for that matter. I remember not getting much sleep!
Good luck!
