Patrick Dempsey has over 60 chickens at his home in Los Angeles.

The 'Grey's Anatomy' star and his wife Jillian have reportedly turned their ''jaw-dropping'' home in Malibu into a bunker with livestock, a rain shower and sustainable garden.

A source told National Enquirer magazine: ''Patrick's estate is jaw dropping. He's got a functioning mini-farm with a huge vegetable garden, over 60 chickens, a fish pond and a pet donkey he's become very attached to. Patrick and Jill have earmarked their place as 'the apocalypse safe house'.''

Patrick, 47, also owns a chain of coffee shops, Seattle based Tully's Coffee, and he has previously said he's considered adding a certain controversial ingredient to the menu, albeit in an ''elegant'' way.

He said: ''Coffee is good for your mind - it's basically a legalised drug. The next step is selling marijuana, of course.

''There's a business model there. You could present it in a beautiful, elegant way: a Michelin-starred coffee shop where you can get marijuana.''
