Deeply Rooted
Luther Burbank used to presprout corn for his market garden (this was before he became known as a plant breeder) to get a jump on his competitors. It let him get his corn harvest two weeks earlier than anyone else. Maybe this would stop the critters from getting your corn seed.Well, I can try, though I'm not sure corn could use up all of its stored food before the root system got bigger than 3 inches.
Rex Stout's sister Ruth Stout (the mother of mulching) had a covered cage built for her corn garden. Chain link, 6' high, concrete foundation, to keep the critters out of her corn. Expensive, but it worked.
Maybe just removeable cages for to protect the seeds till they are up?
I'm sure you've thought of all this and don't need any help.
From some of your posts, you sound like you know quite a bit about corn genetics; have any references you would share?
