2-Legged Chihuahua, fluffy chicken become best friends

(CNN) -- You wouldn't expect a two-legged Chihuahua and a fluffy chicken to become best friends.

But these aren't your ordinary pets.

An animal lover in Georgia adopted the chicken first-- her name is Penny.

Then came Roo, who gets around using a wheelchair.

Their caretaker says sometimes penny likes to steal Roo's treats and chew toys.

But they're best buds and even snuggle together.
