When a Hen's in a Fowl Mood

The eggs tell the story

(HealthDayNews) -- When you're in a bad mood, you probably show it -- by looking angry and raising your voice.

Chickens, on the other hand, send those messages inside their eggs.

According to the journal Poultry Science, if you find an egg with blood, or a brown spot in it, that's a sign that the hen was emotionally distressed. An egg with a pink shell isn't a sign of springtime -- it's an indication that the hen was under very severe stress.

When hens are given larger cages and more room to move, they become calmer, and their eggs start to look normal again.
