I got these hens at a chicken swap. The black one is a barred rock, what are the other two?

I was going to say EE but they have yellow legs and EEs are supposed to have greenish legs. Maybe Welsummer for the one on the left? http://www.feathersite.com/Poultry/CGP/Wels/BRKWelsummers.html (there are some chicks at the bottom)
