An average hen lays 300 to 325 eggs a year. To produce one egg, it takes a hen 24-26 hours. As a hen grows older she produces larger eggs.
Can’t tell if that egg in the refrigerator is raw or hardboiled? Try spinning it! Raw eggs wobble as the liquid inside shifts, but hardboiled eggs spin smoothly. Because older eggs have larger air cells, they’re much easier to peel than fresh eggs.
Have you ever seen a blue chicken egg? There’s a crazy story behind how these eggs garnered their brilliant blue color. According to a PLoS ONE study, over 500 years ago, a virus infected a species of native South American chickens. This infestation resulted in a genetic mutation that triggered an accumulation of a pigment known as biliverdin, which ultimately caused the chickens to produce blue and green eggs!
