There are 100 total chickens who are little who live on the farm. Some are orange, and some are yellow. Although they can speak, the only one who sometimes does is the smallest yellow one. Though they have a habit of causing mischief, they do it "just for fun" or sit in the coop all day. In The Chicken Problem, Cat leaves the door to the coop open and all 100 chickens run wild, and it's up to Peg and Cat them back into the coop before the farmer sees.
