It really depends on the temperature and humidity outside. An egg laid in a nest and not incubated by the hen could theoretically still be edible three or four days later if the ambient temperature was below 50F and above 32F. It is always best to discard eggs suspected to be older than 48 hours uncollected. At the very least they should be candled and given the float test.
Hens typically need 12-14 hours of darkness per day to rest and recharge before their bodies start producing eggs. This rest period helps regulate their reproductive hormones and keep them healthy and productive.
Barn eggs are a term used for eggs found outside the regular nesting boxes and often cannot be determined how long ago they were laid by the hen. Some farms allow the hens to "free range" inside the barn on a farm where they are relatively protected from predators and sheltered from inclement weather. Most hens will lay their eggs in nesting boxes but sometime they will lay the egg in any old pile of hay or straw and are often not found for days or weeks after.
Usually, it can take around 2-4 weeks for laying hens to start laying eggs again after being relocated to a new environment. It's important to ensure they have access to proper nutrition, fresh water, and a comfortable coop to help the hens settle in and resume laying.
18 days - it always takes the same number of days (roughly) to hatch eggs.
Fertile chicken eggs hatch in about 21 days, given warm temperatures and proper movement of the eggs by the hen. If you don't have a rooster in your flock, the hens won't lay fertile eggs and they'll just spoil.
It can take 6 to 12 months before Barnevelder hens start to lay eggs. The exact time is different for each hen.
Hens typically sit on fertile eggs for about 21 days before the chicks hatch. This is the normal incubation period for chicken eggs. Days 1–18: The embryo develops inside the egg while the hen keeps the eggs warm. Around Day 18: The chick moves into position for hatching. Days 19–20: The chick begins breaking into the air cell and may start “pipping” the shell. Around Day 21: The chick usually breaks out of the shell. The exact timing can vary slightly. Some chicks may hatch a little earlier or later depending on incubation conditions and the individual eggs. So, if a hen is still sitting on the eggs after Day 21, a short delay does not necessarily mean something is wrong.
As soon as the male serves the hens then the eggs should be fertilised.
Eggs can stay outside for about 2 hours before they start to spoil. It is best to refrigerate eggs to keep them fresh for a longer period of time.

As long as there is no rooster around to mate with the hens, you will not receive fertile eggs.

As long as no humans collect them or critters eat them, they are very safe if the hens can set on them as needed to hatch.
Roosters don't lay eggs. Hens do.
about a half hour
21 days from the first day conditions are optimum. A constant temperature of 100 F and a humidity of 60% are ideal. Hens will take up to a week to collect a clutch of eggs and then start brooding when enough eggs are collected. Hens will steal eggs laid by other hens to add to her clutch.
