A couple of my shipments had "LIVE EMBRYOS" stickers on them...and my mail lady asked me (with a very worried look on her face) if I didn't mind her asking...what KIND of embryos they were. LOL Like I was doing some sort of human cloning in my basement ROTFL...HOWEVER...I have yet to receive a broken egg in any box marked "LIVE EMBRYOS". I think it's the word embryo that catches their attention and they're not so quick to just toss around a growing creature (even if they have no idea what creature it is! LOL)
