I have three ss roosters, and I have been concerned about one because he attacked a friend while we were working on the new coop. Well, today he got ME! He has no developed spurs yet, so it didnt hurt, but I have a ZERO tolerance policy when it comes to that, even if I lose all my roosters. He is chicken and dumplings this week!!! Anyway, my question is, is that aggression an inherited trait that hopefully I can just cull away from my flock? Thanks!
