Texas has them protected except for ag. damage. I have a local 500 ac pecan orchard that allows me to hunt on. I use taxademied crows and a mouth call. Lots of fun. Also use large enough shot, lead #6 is my choice with IC choke before leaf fall and full after.
My best day has been 50+ birds shooting by myself. Crows are a very smart bird. Good camo and no movement until time to shoot is the answer.
