They've tried forcing Kentucky in to keep his feathers clean – but have resorted to pouring water on him.
'It's a bit too cold for him in the water, so he spends all his time on the rocks just walking around,' said Kentucky's keeper, Adam Stevenson.
'It's a bit of a pain having to go over to feed him because he won't go in the water but he's a real character and everyone at the zoo loves him.'
Aw, poor thing. It's good that he lives in a zoo where he doesn't have to go fishing in the water.
