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...
I'm guessing you live in an area where that's unusual. It will be upper 90's and 100's for the rest of the summer here, and I don't do anything special. There's plenty of shade and places to get a drink. Ours do alright, I hope yours will too.
