I can normally tell if they are hen or rooster, when you can easily see how much bigger or smaller the comb and waddle are! Although strangely this time I was able to say what their gender was when they were four days old! All I did was look at the eye color and see how quickly the feathers were growing in! About the eye color... All I did was see if any of their eyes were more of a blue or a brown, If its blue then its probably a boy, if it brown then its probably a girl! And if you want to look at their feathers all you do is look and see whose feathers are growing quicker, If the feathers are growing quicker then its probably a girl! But sometimes these ways aren't very accurate. If you give me some better pictures of each individual chick then I can try guessing what they are for you. And nice to know that your friend lives in Port Orchard! Does your friend have chickens too???
