Chickpea might be a good bet. I planted a trial plot last year, the Deer went nuts.
Was talking to an old timer at the local feed and seed he said Chickpeas have a high trace element and salt content. Ruminants often have deficiencies in certain elements and this can drive their appetite. Kind of like the cravings you get, your body talking to you.
I've often wondered why a Deer will bypass one field and feed in another field farther away, the mineral content of the food crop kind of answers this question.
It might be a little late for Chickpea, but you are pretty far north.
The plot I put out was mostly red clay and had a PH of 6, Chickpea did OK with it. Odd year last year though, little spring rain and a fairly wet summer (bassackwards). They need some moisture to germinate. Mine came in late and not nearly as thick as I expected, probably from the odd weather.
