eggs are very harty I remember when bruce worte off a clutch when his palce caught fire and i think some still hatched.
I drove from NJ to lower De with aclutch but they were all infertile ( didn't have a light to candle before hand) they took no damage on the trip but then again they were infertile so they went bad anyhow. ) I would onl think of if room to do is warm the water up ( or use warm water ) to prevent a sudden tem spike as the incubator works to bring the water up to temp. ( I always keep a pitcher or couple bottles of water in the incubator so if i need to add soem it already warm and won't cause a lower temp over an hour or so it take to bring it up.)
