Possessive pet duck doesn't want to 'share' his owner

An adorable video has emerged of a pet duck pushing a mother's hand away as she tries to stroke her son's hair.

The footage, shot in Madera, CA, USA last month, shows Nibbles the duck 'protecting' his owner Jonny as his mother tries to interact with him.

"Nibbles watches my every move but is sure to search Jonny's face to make sure Jonny still looking at him," the mother wrote online.
