The ones that I have at the moment do lay well. Even at the coldest this winter, they still were laying pretty decent.
However..
After decades of being raised as a "novelty". And from what I gather, nearly lost as a breed. The pressure for performance wasn't there. We don't live in the day when "on the farm" meant that, what was being raised there pulled their weight. If they didn't perform up to "par", then into the pot they went.
Can they be brought back to that? I don't know. I've seen some nice looking birds posted, but looks doesn't equate performance. As the cliche goes "the proofs in the puddin". Have they been cross bred to the point where that performance ability isn't there any longer? I don't know that either, but I'm hoping not. When I first decided on Dels, everything I read pointed to them being perfect for what I was looking for. Now what I haven't found as of yet, are any that measure up to what is historically claimed.
I've heard many proclaim "build the barn, then paint it". But I don't see much discussion about culling practices that directly relate to the performance of the breed. Which to me is part of "building the barn". I have contacted a couple of people who seem to be actively working towards that, with some measured success, if their claims are true. But I have yet to put my hands on any of those birds to be able to say.
I do know this though. Something that has stuck with me.
