Hi, my heating element seems to have failed sometime between 11.30pm and 6.00am this morning when I noticed. The temperature had dropped to 77 degrees Fahrenheit as the fan had continued to operate. I replaced the heating element straight away and the temperature within the space of a half hour has gone back to normal. My eggs are on day 9 of incubation and have been developing as normal having candled at day 7. I can't be sure as to how long the eggs were without heat but it could have been a max time of six and a half hours. If this likely to have killed the embryos or is there a chance they will be okay? Many thanks.
