> TS sells bag corn for deer feeding for about 10 bucks a bag. I know I will have to plant twice as much or more but I'm OK with that.
I think you will b disappointed with that. Hybred corn does not reproduce well. So instead of getting 100-200 bu an acre potential, you might only get 25-75 bu potential.
Then, corn is real sensitive to plant populations it doesn't like to be crowded unless it gets fed and watered very well, so just randomly doubling the planting population will further reduce yield.
I think that is just going to be a disaster.
You could find conventional corn for $100-150 a bag maybe, that would do ok grain. And you could use a heirloom type open pollinate for silage for cheaper cost.
Just, you do kinda get what you pay for. I understand cutting costs and not shooting for 200 bu yields with the top cost hybreds, but you will be very disappointed using regular old bin run corn, it won't produce many cobs at all.
