How long can incubated eggs survive the cold?

[Chicken_You_Out]

This morning, the incubator was left open by my brother. 8 hours later, I come home and realize what happened. The eggs were about ~5 days along, could they have survived? They’re in our kitchen so the temperature was about 65-70 degrees.

I would keep on going. Candle them at 10 days and see what you have.

They should be fine, but candle as suggested above.
