I've only had one rooster that never tested me as he went into his teens. All others would at least test me out and it's during those few months when a cockerel hits sexual maturity that no kids are allowed in the pen. I train them and those that don't calm down after that surge of teenager hormones get the axe. But it's very common for dominance display in the fall of first year and it takes a calm assured demeanor around them. Children just don't make young males who are "protecting" there girls feel safe and I don't let them near them during that period. Too risky.
