Available zinc should be a concern to any grower particularly of seeds and 
nuts as zinc content is an important nutrient.  Why not test either soil 
content or leaf content of zinc and compare to expected values?

Blank hazelnuts are common - I have seen them many times.  Cecil Farris of 
Michegan used to say that he got nuts every year because he had wide genetic 
diversity in his planting [he bred from many species].  If you're talking 
about just one or two bushes, wait for others to come into production.  Some 
plants just don't perform well at a particular location.
