I've seen ducks drag chickens by the neck to the pond to down them
Ducks are stronger.
Chickens are more vicious and they have beak and claws.
I suppose it would depend on whether it was near water.
Now, if it was a swan that chicken would be a goner. Swans have killed human toddlers.
I'm sure some of those toddlers had it coming
Farm geese may be mean, but they are usually OK if you leave them alone. Polish chickens however, and fucking vicious. They uses to chase me around the farm without provocation.
The battle ground isn't your butt.
PS I'm going to catch you and your going to belong to me @ohphukimintrouble
Chickens are mean, violent and stupid. They win through ferocity and sharp pointy bits.
