Temp swings can be a problem but I would think they would be fine. Do you water bottles in the bator? you need to have water bottles incubator to keep the temps up. Mine can hold temps for a couple hours. You can also keep filling up the water bottles with hot water to keep the temps up when the power goes out. I can keep my bator at 90 degrees for about 8 hours just by putting hot tap water in bottles.
