it takes 21 days from the time its layed and she will only lay as many eggs as she can handle. when she stops laying this is when she will become broody (maybe my hens didn't, so i had to incubate them turning them twice a day) the hen will sit on the eggs this could take two weeks before she sits on them. so have her food and water close so she doesn't have to get up.
Chicken eggs take 21 days from the first day of incubation. Proper temperature and humidity are key factors. Low thatch temperature and drafts can effect the length of time it will take for the chicks to emerge from the shell. When properly done, all eggs in the clutch should peep within hours of each other.
you can preserve an egg for 3 days after the cellby date.
