Chickens farmed for eggs are called egg-laying hens.
A flock of chickens in an artificially lit coop will lay bigger eggs with stronger shells if timers in that coop create the illusion of a 28-hour day.
The temperature of a newly laid hen’s egg is 105 degrees F.
You know that air pocket in the big end of an egg? It doesn’t form until the egg cools down.
The egg always emerges large end first.
If it’s a double-yolk egg, it was laid within six weeks of when the hen first started laying eggs.
Chickens that lay white eggs descend from birds that nested in dark closed places. Those that lay brown eggs descend from birds that nested in light open places.
You’ve heard of those Chinese “1,000-year-old eggs”? They’re 42 days old.
11 percent of the hen’s egg is shell. The white is 57 percent, the yolk, 32 percent.
Those big poultry farms typically gather eggs four times a day.
Some hens lay eggs shaped like cucumbers.
