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.
It can take 6 to 12 months before Barnevelder hens start to lay eggs. The exact time is different for each hen.

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.

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.
