Meet RJ - the chicken who thinks he's a duck.
The unlikely situation blossomed when he became best of friends with Duckie - after the pair hatched at the same time.
The orphans spent every minute of the day together - and now live together in the Gloucester farm's duck enclosure when attempts to split them up failed to work.
Now wherever one goes, the other follows along.
But there's one obstacle RJ can't quite get over - water.
Farmers incubated the one duck egg and one chicken egg at the St James Park Farm.
It is not unusual for animals who were together when they were young to stay friends.
