If the eggs are bad and won't hatch in the normal 21 days they will keep sitting for at least a month sometimes even more.
27 through 89 days
28 days
You should not do this. The eggs that are already there will hatch much sooner, the hen will continue to set on them but the older chicks will bully the late one's and often kill them unless you separate them. Eggs only take 21 days to hatch so if your hen has been on the nest continually for 10 days you are too late to add eggs.
The hen will lay eggs either way, she will lay more if you have a rooster and the eggs will be fetilized

Texas and forty five days
21 days from the time she remains on the clutch of eggs. A broody hen may gather eggs for several days before remaining on the nest continually. Brood hens will move off a nest of eggs for food, water and defecation but not usually for more than 20 minutes each time.
a hen can still lay fertilized eggs up to 30 days after contact with a rooster
This implies a hen and a half would lay 3 eggs in 3 days. Therefore 3 hens would lays 6 eggs in 3 days. So one hen would lay 2 eggs in 3 days. Or one egg every day and a half.
The answer is 2 eggs. Solution #1: Let's get some whole numbers. If we double the number of chickens, we get twice the production. So, 3 hens lay 3 eggs in 1.5 days. If we double the days, we double the production again. So, 3 hens lay 6 eggs in 3 days. Now, divide by 3 to get one hen's production: 2 eggs. Solution #2: To get eggs per hen per day: 1.5 eggs / 1.5 hens / 1.5 days. 1.5 / 1.5 = 1; 1 / 1.5 = 2/3. Now, multiply by 3 days: 2/3 x 3 = 2 eggs.
Once a hen has been mated by the rooster her eggs will remain viable for up to 10 days or longer.
Turkey eggs usually take 21 to 28 days to hatch depending on what they are incubated in like an incubator or by a hen. It also depends on how fertile it is and how it is cared for. It usually takes closer to 28 days.
