Hmm, weird. I have never heard of this. I don't see how they can throw him in jail over that! I would think he would get a fine if anything. Good luck though!
I am also a vegetarian and I just eat eggs from my mother-in-laws chickens that are treated really well so I guess it isn't that bad. As far as milk, I live in Maine and I only drink Oakhurst milk because it's from here and the Maine farmers treat their animals pretty well.
