I have six Beltsville. I am positive they are up to standard and pure. They came from Duane Urch line out of Owatonna, MN. I started with two pairs, had three clutches last summer, hen was a great brooder but not the best mom. Young! and ended up hatching out 27, with 23 to adulthood. I too love these birds. Very friendly, so far very hardy to the extreme weather we have been having in Colorado. I originally got them from bug and snake control and didn't see a snake one last summer and not sure if it was the drought or they did their jobs. Great birds.
