If you have several 20+ bird coveys, I wouldn't be concerned with taking a bird or 2 from each covey. If you have access to dogs I would put on a hunt and do a camera shoot to at least assess what you have in way of numbers. I would hunt the tanks, and the edges of the hay grazer. Hay grazer is a bird magnet this time of year. Those 2 areas would give a pretty good assessment of what you have. Hunting with a camera is almost as good for me as with a gun. It's not as fulfilling for the dog though. I'm like Bill, I'm not as mad at them as I used to be.
