The breeder owns plymouth rocks, splash wyandotte, siler laced wyandotte, partridge wyandotte, australorps, silver laced barnevelders, silver spangled hamburgs and isa browns. I had a family member pick up a mixed box for me and while I can pick the wyandottes, hamburg and plymouth, this ones thrown me because it appears barred. Could it be a partridge but just different pattern? Is it purebred?
