My broody's eggs are on day 9. Last night I moved her nest to a portable nest box. My dad lets them out at 4-4:30 am. When I got home at 4:00 pm she was in her original nest and the eggs were cold. Will the eggs still hatch after a maximum of 12 hours off the nest? I don't know when she got off and switched nests. I have already had to cull 5 eggs for not developing or a cracked shell. There are only three eggs left. I really want them to hatch. Please help!
