i never read anyhting about it in the PA regulations...and ive read about all of it...if its legal and you feel its ethical do what you want...if i was ever hunting and one was running and wouldnt flush i think id blast him like a rabbit....i feel flying pheasants dont have a chance to get away from me anyways...and bird hunting i have atleast one other person with me so if i cant get him they will!wehn they are running on the ground they have a decint chance to get away in my opinion....if it was sitting still i wouldnt shoot though...
