Barnyard (2006)

Otis, a carefree Holstein bull, lives on a farm in the Arizona town of Oedeville. The animal occupants are allowed to reveal their anthropomorphism when humans are not watching them. Otis prefers to have fun with his friends: Pip the mouse, Pig the pig, Freddy the ferret, and Peck the rooster, to the disapproval of his adoptive father, Ben, and the farm's leader. One evening, Otis convinces Ben to cover his night watch, so he can attend a massive party in the barn and impress Daisy, a pregnant cow who recently arrived at the farm with her best friend Bessy. As the farm animals party, the sadistic coyote Dag and his pack attempt to raid the farm's hen coop. Ben arrives and successfully fends the coyotes off alone, but is mortally wounded. Otis rushes to Ben's aid, but Ben dies in his embrace. Following Ben's death, the animals elect Otis as the new leader. He struggles with his new position and duties, which include salvaging an incident in which the farmer witnesses the animals partying and Miles, an elderly mule who was Ben's best friend and assistant until his death, knocking him unconscious. Leaving Freddy and Peck to guard the chicken coop, Otis joins the Jersey Cows, a trio of trouble-making cattle, in getting revenge against Snotty Boy, a cow-tipping bully. After narrowly avoiding the authorities, Otis returns for his night watch and shares a tender moment with Daisy, who recalls the time her late husband and fellow cattle were lost to a storm. Otis soon encounters Dag, who easily deters him by exploiting his weakness as a leader and guilt over Ben's death. Dag arranges to periodically steal animals from the farm, threatening to kill them all if Otis interferes. Ashamed, Otis decides to abandon the farm, but relents after learning that the coyotes have kidnapped the hens, including Etta and her young daughter Maddy, during the day behind his back. Encouraged by Miles, Otis sets out to confront Dag alone at his wrecking yard den. Initially outnumbered by the coyotes, Otis' friends arrive to fight alongside him. Together, they defeat the pack, with Otis warning Dag never to threaten their home again. The animals hijack motorcycles and drive home, where Daisy gives birth to a calf named Ben after Otis' father. Otis vows to protect the farm as his father did before, watching the stars form images of him, Daisy, and young Ben dancing together.
