Long story short, I'm in a disagreement with a friend with how long eggs can sit before being placed in an incubator. He's being so disagreeable that unless I provide him with a scientific paper about it, he just isn't going to listen to anything I have to say about it. Could someone please link me to some sort of professional paper? My understanding is that they can last 7 days, 50-60 degrees F, large end up, being rotated twice daily so embryo doesn't stick. Correct me if I'm wrong, god knows he will. Thank you!
