I always make a point to say to any kids thst they are not to go into the pens without me there. I don't care if that sounds mean or not. Said it to the relatives and my kids friends. I know some kids are ok with animals but until I know them and can trust them...no way. If they get out of line I tell them to stop in a not-so-nice voice and to go see their parents.
Sorry for your frustration.
