First of all, you cannot go by breed to determine temperament to any degree of certainty. Secondly, small children should never be allowed around roosters due to the hazard of them losing an eye to a rooster jumping up to flog--it's not really the rooster's fault in that case. Children have jerky, sudden, movements and are loud by nature. They can make the calmest rooster nervous. Even the sound of my neighbor's infrequently visting grandchildren several hundred feet away, yelling and screaming, puts my Isaac, a super friendly and easygoing rooster, on edge.
A rooster is like a bull or a stallion, just in a smaller, more agile package. And you'd never allow small children around those, right? Same deal. Best to keep a fence between them until the children are older and can be taught how to handle the rooster.
