There are a few black and white ones that look like they could be SLW mixes, but it's hard to tell.  I wouldn't keep them just because they're part SLW...  it won't mean anything great.  They might turn out to be excellent layers, and they might not.  It's just a guess at this point.  If you don't like their personality, don't keep them.  There are a lot of great eggs available from other BYC members, and you might get exactly what you're looking for on here.  
Can you send a message to the person you got the eggs from, and find out what they're mixed with?
