You Can't Eat Ducks

I've been wondering when/if Abby would react negatively to references to people eating animals. Tonight I was reading her Toni Morrison's The Big Box. A girl's parents bring her a duck prepared by a chef. Abby asked, "Where is the duck." I pointed to the picture of the cooked duck on the platter. Abby looked at me and said in a rather high-pitched voice, "You can't eat ducks!"
