I have two roos as of now and they aren't aggressive, but they just kinda look at me like 'get away from me and my hens' so, I don't know if that's the beginning of aggressiveness? or what.
Also, I got some new chicks!!!, yay!!
being friendly and being non-aggressive may be 2 different things. my EE roo is totally non-aggressive to people, but also has no desire to be within 50' of you either. my dorkings and SFH on the other hand, are under foot constantly and frequently having to be nudged aside so I can actually walk somewhere. LOL a couple of them, even the dog has to either jump over or push to get where he's going. LOL
