Hi there--I am on day 16 of incubating 48 chicken eggs. They were checked last night at 10pm and the temp was at a steady 99 degrees. But this evening at 6pm the temp was down to 70. We put a heating lamp on them and got up to 90 and ran to get a new incubator which they are in now. The heating element went out on the old incubator. Will this temperature drop kill the chicks? I am so worried that this did them in. Any ideas or similiar stories with good outcomes?? thanks!
