We bought Rural King's version of Cinnamon Queen day old pullets. Rural King says the are red sex link females from RIR rooster and SLW hens. We'll see? They look exactly like the pullets labeled Welsummer in a separate bin of Rural King. I'm not very confident in the staff of big box stores. I'll post some pictures to get some opinions.
TSC has the same problem with chicks being mixed up (at least the ones I've been too). If they are Welsummer's, I think you hit the jackpot...they're wonderful birds and lay beautiful eggs.
