try thinking of a theme.
think of a strong interest or subject,such as influential people,computer games,tv shows etc-then have a look through various names from the theme that are available to see which ones fit best.
because the last flock of mine are living here/a residential centere,the autism service which runs here made a webpage on their site about it-
http://fairfieldresidential.co.uk/index.php?pageId=69 inc old pics/vids and descriptions of each name.
the next flock who will be born in like a week or so will have a theme to,hopefuly something influential as its something to think about and raise awareness as well.
