galloid
A chicken-shaped thing that might be as dumb as a chicken, but sometimes acts like it's got a brain the size of a pebble.
My neighbor's pet galloid tried to peck my eye out. It failed. Twice.
At the zoo, the galloid stared at me like I was the dumbest thing it had ever seen.
I gave my galloid a math test. It circled the answer. Then it pecked me.
