Eggs at 87% humidity and 89.6 degrees?

[molly1chickens]

My friend had a incubator malfunction and has kept her chicken eggs at 86.6 degrees fahrenheit and 87% humidity for their first week. I told her this was lethal to her eggs and she should start again as her eggs are probably all dead. Is this correct or is there a small change or survival or something?

At 86.6 degrees they likely didn't start to develop at all. You can have her candle to check to be sure but chances are the eggs never heated up to start growing.
