I never use a heat lamp. They are a fire hazard, especially around animals. Chickens in this area will be fine as long as they have a dry place to call home.
Do like Chickielady said and run the incubator at 40% humidity for the first 18 days. In the winter if you run a furnace or wood stove like most people do, the humidity inside your house can get quite low despite the rain outside. You should follow the instructions with your incubator and add...
I just want to warn you that I got some Wheatens from a guy near Olympia. I don't know where he got them, but they had the recessive short toe gene and all of them had the little toes. The one with the nicest coloring died, and I culled the others. Just beware when you are looking for...
This weather is extra ridiculous considering they predicted a mild and dry winter. LOL Whoever complained about it being too hot this summer is now punishing the rest of us.

There shouldn't be any problems borrowing an incubator. Clean it out really well and wipe all the surfaces with a 10% bleach solution and let them air dry.
My recommendation is to do a test hatch on cheap eggs before you spend a lot of money on more expensive breeds. Regulating some...
It helps to keep the humidity higher since the air cells get so big when they are "saddle sacs". You should hatch them in an egg carton with the air cell end up. I have hatched saddle cell eggs before. It isn't ideal, but can be done.
HenKat - You have a beautiful coop for the girls. They will be fine in there during cold weather.
About the water on the floor - you shouldn't put anything like straw or shavings down since it will soak up the water and you'll end up with a mess. The water isn't going to hurt the chickens...
