Growing sweet corn -- Need some help.

I am not one to grow much corn as you can see from the photo (I do have another patch about this size of popcorn elsewhere on the property) but I like to have some sweet corn and as ya'll know, sweet corn Starts to turn the sugar into starch the second it's cut -- fresh is best always with sweet corn.

Okay, so... this is the third year I've had sad looking corn and am not sure what I need to do for it (funny as I was born in Iowa, the corn state state) -- when I say sad, it's not having buggy issues, rot, or anything like that, but I just do not get big cobs with plumb kernels (more like half size), any suggestions?

Below is my wingless bantam rooster that I saved and rehabilitated (at some point I'll do a post on him and healing stuff for the yard animals), Mr. Willie, I'm posting this for Hive account@lifemovedbysteem as we've talked about him. I had to use zoom as he's in a mood today controlling the ladies. haha. One wing only made him more of a rooster. :P
