These sorts of laying problems are not the norm and if not addressed can lead to serious problems. Did you finally find a vet you trust? If so, call them and ask for their opinion.That's what I hope. This is only my second round of ducks. My first round of ducks laid perfect eggs. They gobbled down oyster shell like a teenager scarfs fast food. I'm a bit flummoxed by this year's egg laying issues.

I too have had a couple of bad experiences at a place in Cupertino, so I know how you feel. The one place I have never had a bad experience at is in Monterey, but that is a very long drive for you.
