I've been wondering because I've not had time to address the rooster issue but at the same time he's not tried again so I'm a little confused... I'm not good at culling a chicken 'in cold blood' but if he tries again I will not have a problem ending the problem. But again I haven't had time to mess with them at all. I don't have a problem making them move when I change out their water or feed. If I walk through, they give way to me. So was he just checking to see where the boundaries are or, as I suspect, will he get bolder the older he gets?
