Barred Rock or Sex Link?

[BuffOrpingtonGA]

I got these this morning, 10 of them, and the boys at the feed store had no idea. I'm kind of new to chick ID-ing, but I'm thinking maybe Barred Rocks?

They look like Barred Rocks to me, but they could be male Black Sex-Links.

Are the legs pink or yellow? I think they may be barred rocks as well
