Corn for Thought

In addition to my post below,we also have a small spattering of the other sort of corn - err, corn. Field corn? It’s been growing under the crab apple all summer. I thought it looked good, especially as we have lots of poppies growing close by. It’s also been a handy place for wildlife to shelter, and I took a picture of one such resident:

I have been wondering if I can do anything useful with the corn though. I can’t really see myself grinding it down by hand with a pestle and mortar (partly because I don’t own one). So my little project is to find out harvest corn, how to mill corn by hand, and how much you need to do something decent with. Corn chips, anyone? Does it make flour easily? Am I completely on the wrong track? It’s actually quite embarrassing that I’m so baffled by the whole thing.
Anyroad, I’m not totally opposed to the idea of having a mini corn field here next year. The only problem is the chickens and cats have a tendency to sit in the middle of it and flatten it…more investigation needed me thinks.
