If they are lockjawed This is were your Woodsmanship comes into play find a area that you knowthat has had nice birds in the past ,set up and do not call loud , soft stuff only do more watching than anything do not call alot eather , BE VERY PATIONT DO NOT walk around alot calling you don't want those birds finding out that you even exsist in the world !
They will get cranked up again , but if you call to much or to loud they may never get going again .
TAKE YOUR TIME TAKE YOUR TIME !
Good luck brother Smoke one for Me!
