RE: they already picked it clean...now what?
With only a quarter of an acre, pretty much any type of forage you plant will be picked clean. An average deer can eat 7 lbs. of forage a day (dry weight).
My suggestion is if you do plant something, I would probably plant at double the recommended adjusted seeding weight. The reason for that is your plants probably won't make it to maturity to compete with one another, and you will have a pretty high incidence of mortality in some of your smaller plants. They will be under a lot of grazing pressure if the deer are looking for them.
Now, keep in mind, that's not double the seeding rate of rye per acre + double the seeding rate of peas per acre + double the seeding rate of clover per acre, all multiplied by a quarter. You have to multiply each one by the percentage of that plant composing the mix.
