...would it be possible for an egg to hatch without a hen on it? The temps have been in the mid to high 90s and humidity is really high. Could an egg left out in this possibly develop? At night it drops to about 80. Would that do it in? I know my hens that are sitting have shoved all the eggs to the perimeter of their feathers and are often crouching over them instead of sitting on them. I assume it is because of the weather. What do the incubation pros think?
