Hen left her nest

[jdeppe02]

I have a have a chick that started to sit on a clutch of eggs. She sat on the clutch for two days then got up and left them for two days. She is now back sitting on them again. Will they hatch?

A cool down in the first week of incubation may not hurt them.
Here is a good read on effects of temperature at various stages.

How long had she been setting day and night before you gave her eggs?
