I found the same thing—my hen-raised rooster is ideal, polite, a real gentleman. The 2 boys that I raised became human aggressive and so they are no longer around. I don’t know what I did wrong, but I noticed that my little hen puts her boy chicks in their place, she’s quite aggressive twd them from about 3 weeks on.how awful he is. He was raised by me. The other is a mutt, same exact age as the maran, but raised by a hen. He's the ideal rooster
