Age. A hen’s age is perhaps the most important factor that determines the size of her egg. However, the correlation between age and egg size isn’t exactly a straight line: pullets and young hens have been known to lay eggs on both extremes of the size spectrum, from peewees to jumbos.

Where do hummingbirds go at night?
Hummingbirds often find a twig that’s sheltered from the wind to rest on for the night. Also, in winter, they can enter a deep sleep-like state known as torpor. This odd behavior usually happens on cold nights, but sometimes they go into a torpid state during the day.
