Our boy is only 9 weeks old. He is not aggressive but will "chase" the dog (he is in the run and she is outside it) and I'd like to prevent people aggression rather than have to deal with it later when it's harder. I have had an aggressive roo and at the time (20 yrs ago) didn't know what to do and ended up rehoming him where he became dinner. That one was a RIR and I know they can be more prone to aggression and Cosmo is an EE and I have no idea how they are (I've only had girl EEs before-that was back when they were all called auracanas). The only thing I've done is crowding him (just walking toward him) when I'm in the run. He always backs off or goes the other way. Is this ok to do? Should I continue and should I encourage the kids to do the same?
