Do barnevelder chipmunk stripes have to be white?

[Mudda Clucka]

Got a couple Barnie chicks, but the chick in the corner doesnt have white stripes, and It has a much chunkier, rounder shape, is it still a barnie? Thanks!

I forgot to mention it still has the yellow legs and single comb

Barnevelder chicks are variable in color. If the one chick is more plump, well, chicks are variable, too. I think you can assume they are all what they're supposed to be.
