I had a hen go broody so I gave her some eggs on April 20th. Yesterday I found her nesting(brooding ) 3eggs in a different box. Her original nest was occupied by another hen laying her egg. I think the broody got the boot but I'm not sure how long she had been off the nest. He r original eggs felt like warm(like they may have been not brooded over night and the layers reheated them while laying that morning. I put the originals back under broody in her new nest as I think no one will boot her out of that nest(the others tend to not use that box). My question is how cold can 10 day eggs get and for how long before they are no good or wrecked from the cold. Should I just give her new eggs or wait and see? I've put 4 new eggs in withe the rest just in case but wondering your thoughts.
