I dunno if ed is trying to keep you away, or if he really is ignorant about game bird populations in NH. But, a quick look turned up this website.
https://www.wildlife.state.nh.us/hunting/birds.html and
https://www.wildlife.state.nh.us/hunting/small-game-outlook.html. Two quick quotes from the site .....
"Ruffed grouse were the most sought-after small game species in New Hampshire, accounting for 62% of hunter-hours in 2019. Although most abundant in northern forests, good numbers exist throughout the state."
"New Hampshire's grouse and woodcock populations are abundant and healthy."
Just sayin' SRH
