Yep, the Bielefelders are awesome! Hands down the biggest layers I've ever had - ALL the hens lay like that, and I've never had a double yoker! On another note; I found a teeny tiny egg from God knows who, that was a double yoker. The yolks with whites combined were no bigger than a tablespoon. Bizarre!
That is excellent information to have. When I can sneak another batch of chicks into the coop when DH isn't paying attention, I'll definitely look for a couple. =)
