I wonder where your barnevelders came from. I have those, they are beautiful and easy going. I hatched mine.
Most of my Barnevelder stock is from Jan and Paul Anderegg in Iowa. They own Rainbow Gate Farm. I don't see Barnevelder listed for sale on their website, though. Maybe they are not breeding them any more. I have a few from DGibson here on the Okie thread. He's got some really beautiful birds.
