I have a white leghorn rooster that came from the Humane Society. He was originally one of those dyed Easter chicks....survived that, adopted by me, and I got him a couple of EE hens. He should have lived happily ever after....but, oooooh, noooooo! He hates my guts. He has flogged me several times and I have knocked the fire out of him several times for doing it. Usually I throw something at him, and miss though. He will sometimes quit for a few days...but always, always comes back after me. My mother raised chickens and one of her white leghorn roosters jumped up and spurred me one time, hit the quick of my fingernail and I ended up losing my nail....horrific pain when it happened....and he ended up in the stew pot. She never kept a rooster that was mean. The thing is....because I haven't killed him, he obviously thinks he is winning....and I am keeping him for now, but as soon as I can find another rooster, he will be humanely put down at the shelter. I have never seen him mate with one of the hens. The eggs don't look fertile....don't have that little spot you see in fertile eggs. He will usually follow them around, but he isn't like other roosters I have had....attentive to their hens. I'd keep the mean old devil anyway, if he wasn't bent on fighting with me. I'm in my mid 60's and I am too old for this...know what I mean? My question.....are some breeds just more aggressive like that?
