My seramas laid some eggs a few days ago when the temperatures were between 40 and 60 degrees (3 different days). The hens were sitting on some of the eggs and some of them were in the lay box unattended. At what temperature will the cold kill the embryo? I was hoping to incubate them tomorrow along with some recently purchased eggs but don't want to take up the room in the incubator if it's a lost cause. Thanks for any help
