Just because a bird gets pressured.Doesn't mean he's gonna stop breedin.Long as he's in that breedin mode,He's killable.You just can't use the same tactics as on non pressured birds.Ya gotta do what the real hens are doin.If they won't come to a call(man made or a real hen)then they won't breed and the species is gonna die off(of old age) Ya just gotta give em what they want.I was walkin into a Pa. state game lands late one mornin.Another guy was on his way out.He said I might as well turn around,they weren't talkin.25 min later I carried a bird out.
