I'm hoping to get some chicks for a brooding GLW I have. I have a question about the possiblities. She has made a nest and put some eggs in it although I don't know how many. I can't see inside it. She still goes in the coop at night and that is my concern. With the colder nights we're starting to have, just how cold and how long with her off the nest will it take for the eggs to be none productive? If they did hatch, the cold and the chicks I'm not worried about. I'll leave that up to mama. Just don't know how much cold the eggs can take and still be usable. I hope this is in the right place.
