Owner Yang, of Anqian village in Fuqing, said the hen moved into the dog's kennel after it gave birth last month, reports Southeast Express.
Since then, the hen refuses to leave the kennel, staying inside all day and only walking out when the dog is nursing its puppies. Yang says the hen is very protective of the puppies and refuses to allow strangers to come close to the kennel.
"Quite possibly the hen is envious of the dog because it has no offspring of its own, and so it is trying to take over the puppies," he said.
"The dog seems to have given up the idea of driving the stubborn intruder out and has decided to share the space with the hen."
