I had 30 eggs in the incubator and I mentioned before that they were from a questionable source. However the due date came and six hatched. I am very grateful for that. They are doing well. Then last night my 2nd incubator which had my duck eggs, bulb blew during the night, and I woke up to the eggs at 70 degrees this morning. They are on day 22 so I think they may be ok, as I am hoping. Im just posting this because sometimes things go beyond your control. I've had super hatch rates and terrible ones. I guess the only thing to do is try to make sure it doesnt happen again. I am re designing my incubators with alarms and backup in them as soon as these hatch.
