Light bulb blowed (blew?) on my homemade ice chest incubator. And the temp droped to 86' F for a few hours on 2 week old duck eggs. Never learned/tried to candle eggs. I guess I need to learn how. Do you think they are still alive? I'm going to keep turning them till day 25 and hope they hatch. That light bulb had been a good one. It had been on for the last 5 months flashing on and off ever few minutes. As soon as the incubator becomes empty again, I'm going to add another light socket, So they will be 2 bulbs. Just in case one blowes again. Thanks, This was my first post here.
