Public dove hunting around DFW can be a real zoo, especially if ya find birds. Late season you might find a decent spot when some migrators get here and the pressure lets up, but on opening morning and weekend be prepared for anything.
Not trying to depress ya or talk ya out of it. I hunted a place adjacent to some public hunting in Collin county around 5 years ago. I was way up on the north end away from it but I drove by after the opening morning hunt out of curiosity. There were so many trucks parked along the gravel road there wasn't any room. Folks were stacked up in the field like a grid pattern every 25 yards. Not my thing.
I know in less populated places where there's public spots you can do some good without the circus.
