West Virginia is trying to reestablish quail. They are stocking 6 WMA across the state with 20K birds. This is a 5 year project. They, the state, have done a pretty good job(in my opinion) concerning the habitat on the WMA.
When I run my rabbit dogs, we flush coveys of them. I used to see tons of coyote scat where I run my hounds, last time there I didnt see any scat. I think they may have done some predation work but I do not know.
I hope it works, time will tell.
