Hens don't "yelp, they "yap". When they get going, loud and non-stop they remind me of the human species of female.
My mouth calling has gotten better since I stopped using "chalk" as a reference word and actually started using "Yap." Well, it sounds better from my perspective. I can get a better high to low.
Some of the phrases I use are left overs from the Navy:
Don't nuke it. (stop overthinking things)
He's done training (dead turkey)
Snoopin' n poopin' (stalking)
We had to ditch (get out of the area)
