Yes that's a salmon Faverolle cockerel. And they are generally very docile, sweet birds, but you never know how roosters will react to young children. With very small kids, it's always a different ballgame, they move very differently than adults, for one, and they don't know how to interpret animal body language. Also, any rooster can mistake a child's exuberance around their hens as a threat.
I wish I had better advice, but I don't think that having kids under 6 or 7 around large fowl roosters is advisable, though people do it successfully all the time. ...
