depending on time of year obviously, but all offered up at once...i think you already have the order pegged. I dont have much experience with wheat though.

I know when certain acorn trees are dropping, there could be wolves patroling it and those deer will still find a way to get to them acorns. and soybeans seem to be preferred to corn during the summertime.

but late season once most foods cease to exist, a standing corn field can be a gold mine.

All about timing of when you hit each of the sources.
