We purchased 5 buff orpington pullets from Rural King 12 weeks ago and one is white and does not appear to be a buff. At 2 weeks old, Goldie was the largest chick and now at 13 weeks old, the others have outgrown him/her. I suspect it is a roo, but am not sure of the breed and have nothing to compare with. Rural King did not stock any white chickens at that time (only orps, RIR and Barred Rock in stock), so we are really at a loss. It does have one black/white striped tail feather, a couple a brownish spot on each wing and some black flecks in the neck feathers.
