Think of it like fertilizer.  It gives a big boost initially and then the effects fade as time goes on. 
I personally put it in when I till and occasionally put a bit more around roots part way through the growing cycle. As I have multiple seasonal garden areas and projects I continue to use it most of the year. Even when I didn't use it that much the only time I had it get piled up was in the fall time when composting lots of leaves.

oo)   I'm sure some one out there will correct me, because I'm flying by the seat of my pants here.  This is my first year working with chicken bedding in the garden, so it will be a work in progress.  Dirtylittlefly:  Regarding your neighbor and the statement about nitrogen binding... that has been the accepted story for years... but more recent experimental methods are proving that it ain't necessarily so:  You might want to do some reading about the Hugelkulture and the Back to Eden methods.  Both of these gardening methods fly in the face of the "nitrogen robbing" theory.  In my experience, i've noticed lush growth around any patch of ground mulched by any woody product.  So:  I'll be doing my own little mini Hugelkulture/Lasagna gardening mound in the garden, made for the most part of those nasty nitrogen robbing shavings from the coop.  I'll keep y'all posted about the success/failure of the project.  (I thought that if I inserted a y'all, it might hasten the demise of the 4' high pile of snow in my garden.)
