I agree. I have done things like caught a roo and put him in isolation for a few hours, but still with the flock.. just in a large dog kennel alone. I have picked up a roo and walked around with him when he was young and sized me up. Usually I just put my boot slowly and gently up to their chest if they come too close and force them to take a gentle 2 steps back so they learn the respect of space. My roosters eat out of my hand and I make sure that they see I am the food/treats and water source. Some people say omggg never ever do these things!!! but all of these things have worked for me. I will add that I only did these things when they were young/not matured and without spurs. Every rooster I ever hand raised myself has never been fierce. I have had Australorps (which they say are bad), Buff Orppington's, EEs and Plymouth Rock. Never once did one attack me. Each rooster is an individual and will react to how it is treated. Good Luck!
