Jennifer Aniston — My $21 Million Mansion Has a Chicken Coop

And they say women lose 90% of their eggs by age 30 … Jennifer Aniston“s newly refurbished, $21 million Bel Air mansion is a grazing site for chickens.

44-year-old Aniston and her fiance Justin Theroux just completed renovations on the sprawling 3.5-acre property — which the couple purchased last year — and Aniston decided to maintain the chicken coop.

FYI, Bel Air is one of the most exclusive neighborhoods on the planet … and here”s a fun fact — the house featured on “The Beverly Hillbillies” is also in Bel Air.

Who”s no spring chicken now
