The two penguins have started placing stones at the feet of parents before waddling away with their eggs, in a bid to hide their theft.
But the deception has been noticed by other penguins at the zoo, who have ostracised the gay couple from their group. Now keepers have decided to segregate the pair of three-year-old male birds to avoid disrupting the rest of the community during the hatching season.
A keeper at Polar Land in Harbin, north east China explained that the gay couple had the natural urge to become fathers, despite their sexuality.
"One of the responsibilities of being a male adult is looking after the eggs. Despite this being a biological impossibility for this couple, the natural desire is still there," a keeper told the Austrian Times newspaper.
