Rye germinates in the pickup bed, on the flat spot by the PTO connection, on the brush hog and on top of the tractor rear axles and it grows in those soil less spots. That is just from either spreading it or driving thru or brush hogging a rye field with seed ready. Last year the deer preferred the winter wheat over even BFO oats and way more than they did when the fields were mostly planted in rye in 2016 and 2017. Some years the deer preference is not so obvious and most years here nothing touches BFO as far as deer preference. The winter wheat fields this summer have so many weeds in them that harvesting clean seed is not possible. Had very few weed seeds in the rye and triticale fields harvested in 2017 and 18. Rye is the first green here when the snow melts. So rye is both better than wheat and not as good as wheat depending on the goal. That is why rye and wheat were hybridized/crossed to produce Triticale(hoping for the best of both worlds). Given a choice, I'd use all three in the same field to feed deer in the fall, winter and early spring and to hide fawns come spring. If I had to use just one it would be Rye here. Luckily all three are usually readily accessible here.
