No, he wasn't a jerk. He is just a normal guy trying to do his job. He did try to pull that "official" BS with me to start, but I made it pretty clear that his badge didn't frighten me. By the end, we were chatting just like normal people would do if they met through mutual friends.
As far as socialization, I'm not a model source. I tend to interact with all of the critters I meet and have always had good luck in getting them to tolerate me. The ducklings I have are wild mallards and I want them to leave when they can fend for themselves but when they scooted out today I was able to call them back with some peas and calling to them. My chickens are generally more accepting of human contact since I started groping them.
It might also be a breed thing. The silver laced Wyandottes I have in the brooder are pretty flighty while the ISA and BSL's don't seem to be all that skittish with me.
And while I'm typing this, my cat is draped over my shoulder like a sack of warm purr. I swear she has no bones in her body.
