Ok, I will admit I felt a little weird eating my first parrot egg. In my defense that was before I started keeping chickens.
I live in a farming community, and teach young children at a private school. Even though some if them LIVE on farms (they may understand keeping bulls separate from cows/calves) I'm amazed at what I do have to teach them. One little girl wanted to argue with me about roosters laying eggs. None of them can tell ducks from geese. I'm also surprised at the resistance I meet. As a whole, they don't WANT to know that meat comes from animals. Or that roosters CAN be dangerous to young children (along with bulls, buck goats, and pigs, etc.). I find myself walking a fine line between educating them about farm facts and not upsetting them. They know I have chickens, geese, guineas, goats, rabbits, llama, etc. and are always wanting me to talk about them and show them pictures.
But no, they actually didn't know milk came from cows either (or in my case goats, which REALLY messed them up, LOL!).
