How do you know the sex of a chicken when it has hatched?

Answer 1

It's very difficult. First you have to gently squeeze them so poop falls out, then you check their bottom and look for a lump, which is a male's sex organ. It is very difficult and only professionals can do it accurately. I've tried it with no success. The easiest way is to look for a personality. If they seem bossy and pick on others, it may be male. This also isn't always accurate. The next way is to look at their tail feathers. If they are short, most likely it's a female, roosters have longer tail feathers. This method is most accurate for me. Of course after 6 months whether your rooster crows or your hen lays an egg will be 100% accurate. My grandmother, who was an avid chicken person, once advised me that you can pick the chickuo by the scruff of the neck. Hens will just basically hang ther and not fight. Roosters on the other hand will flop and fight. With that I can get a 7 out of 10 ratio
