I've got a broody hen that left the nest today, which by my best calculations is day 23. Is that a good indication they aren't going to hatch? I tried candling with a flashlight inside a tp tube, egg on top, but to my untraied eye, they all look the same, except for 1 that the light doesn't penetrate. I'd guess that one to have a chick in it, but mom left early this morning while it was cold out. Would it even still be alive?
BTW-the candling pictures are great for someone like me that doesn't know what I'm looking at or what to look for, so thank you!
