My new red sex links get along so much better than my mixed hens ever did. I can't even tell the pecking order with them. The first chickens I had always had a very clear pecking order and the barred rock would attack others when the rooster mated with them. These red sex links are just fine with anything, not once have I saw one even peck at the other. I have to say I like them a lot better, as the old ones had bare red skin behind their heads from the barred rock attacking them, when the rooster was mounted. Is this a trait of red sex links?
