Chook Me! - how do you tell the difference between roosters and hens when they're babies?

how do you tell the difference between roosters and hens when they're babies?

i have 4 chicks, and i don't know how to tell the difference between them. i'd like to know.

This is no joke, it works. Hold the baby chick in the V part of two fingers by their head. A hen will be docile. A rooster will jump around.
One of the most common methods to tell the gender of chicks is called vent sexing. It literally involves squeezing the feces out of the chick, which opens up the chick's cloaca slightly. If a small "bump" shows, that means that the chick is a male. Some females have very small bumps, but rarely do they have the large bumps that male chicks possess. Feather sexing is also used, but requires that the chickens be specially bred to manifest their gender in differences in the feathers as hatchlings. Female chickens in these breeds have longer wing pinfeathers than the males.

I'd say: it's hard. My friend got some chickens- laying hens- and they were a couple of weeks old... all looked the same. He went on vacation for a month, came back and- lo and behold!- one of his hens had turned into a rooster!
