is this egg still viable?

[preciouschick]

so i have a broody silky. i took some eggs from her which should of hatched and put them in the incubator. she was still sitting on an empty nest. I felt bad an decided she could keep 2 and put them back. So this morning, i she decided she was done and left the 2 eggs alone in the coop. the eggs got cold. Will they still hatch or can i assume the cold killed them. I did candle them and i dont see movement, no internal pip.
I am in southern PA. it was cold last night.

Put them back in the incubator. If they are at the tail end, they are creating some heat and can survive without the hen for some time. You don't know how long she has been off the nest.
