My mother drove to Massachusetts one day while I was at school and bought a lamb for me. I think this was shortly after a visit to the orthopedist, which usually left her feeling guilty about not catching my hip displaysia until it was too late to do anything productive about it. So she bought me a lamb.
There is very little in the world that is more adorable than a lamb. They leap around in a way that makes you feel joy in your heart. The problem is that lambs become sheep, and sheep are so boring and dull that it breaks your heart. Watching a lamb turn into a sheep is enough to make one want to die before they get old. We had Sean for about 8 years, and then one night he was mauled by either a coyote or an uncontained dog, and we had to put him to sleep.
Onto the evil chickens.
My sister hatched a bunch of eggs for the science fair when she was in 5th grade. We had a dozen eggs, and 5 of them turned out to be roosters. Chickens are fairly aggressive animals to begin with, but with that many males, these guys were the most ornery bunch of chickens ever. Instead of turning on each other, which roosters are well known to do, these guys banded together and took out their fierce aggression on us. They would hide under bushes, coming out to attack your ankles when you walked by. They would attack your hand when you went out to feed them. They were nasty little buggers.
Now, I respect vegetarians, but my experience with chickens taught me that chickens are inherently evil and deserve to be eaten.
