I just got back from that area last night and the pressure there is unreal. I've seen fewer hunters out on opening weekend in some areas than what I saw there. I hadn't made motel reservations figuring it wouldn't be an issue this late in the year. Come to find out the motel in hill city and in Stockton were full.
In 2.5 days of walking I never pulled the trigger on a rooster and really didn't even see that many except for a couple of groups that were on private land. I did get some good dog work and points on hens and quail so it wasn't a total bust. Also saw some chickens but I mistook them for hens at first and then had to look to see if they were in season. Of course never I never had one fly close enough to shoot at after that.
Before you fire a shot at the Chickens make sure you buy a PC Stamp - $2.50 and required to take one.
