The story of the boar bacon upthread reminded me of the time I cooked a rooster! lol I'm serious. Many years ago, when I was in my twenties, I lived near my parents house and went over to get something from their freezer to cook, so I didn't have to drive to the store.
My mom normally had ground beef, steaks or some chicken in there. Unbeknownst to me, a family friend who ate odd food, had brought my mom a rooster to cook. My mom had no intentions on eating it, but had put in in the freezer. I guess to be polite. lol I then took it home, thinking it looked large and and tough. It was so tough, I couldn't eat it. My mom got a big laugh out of it.
I have since learned that you can eat roosters, but not when they are large and haven't been castrated.
