I start my corn in the greenhouse and transplant into 6 rows 12’ long with plants spaced 12” and rows 30” apart and hill once or twice. These rows are flat until I hill with a garden hoe (vs a street ho) The way you planted a common and accepted and I had a attachment for my Wheel Hoe that made furrows for my corn until I put boards around the raised beds. I water with 1/4” drip line laid down each side of the corn (and other crops). and yes you can transplant that wayward corn seed but take a deep plug to get most of the tap root.

If you don't want to transplant, plant the corn seed at least 1 1/2 inch to 2 inches deep,
and the crows will give up trying to dig the seed you to eat them.
Also the sprouted plant will be deep enough and the roots established well enough
that the crows can't easily pull them up to eat the seed ball off the bottom.
