Old varieties aren't. Look up Dominiques and Javas. They're known as "heritage" birds.
Ducks are much nicer.
I trained the ducks to line up for feeding and they would wait in the pen while I collected the eggs and cleaned up the joint. Then when I tapped three times on the door they would file in.
I always felt a little sad eating duck. Chickens not so much.
I like chickens. We had 3 for pets until the raccoons moved in and we knew it was a mere matter of time, so we gave them to a friend who often keeps chickens. She’s down to one now (too many foxes over there) and it follows her around whenever she’s outside. DH used to play with our chickens a lot, they were very friendly. They were auracanas (sp?).
