Social icons in header-left

Hi, I would like to put the social icons not in a footer widget, but next to the logo in de header. I'm already using a child theme and I suppose I have to edit the Custom-header.php but I do not know where and what code to insert. Could you please help me out? Here's our website: http://bit.ly/1fQH8Pz The social icons are now in the footer.
