A grazier near Aramac in central west Queensland is facing an unusual fertility problem with her cattle herd.
Margaret House says her pet emu, Loui, believes she's a cow and competes for the Brahman bull.
She says Loui has found her mate and isn't prepared to share.
"She's been out trying to mate with the bull, all the time she lives with the bull, she follows him everywhere, she sleeps with him in the middle of the day by the dam and the problem is she won''t let any of the cows near him and she won't let him serve any of the cows.
"So we've had to put other bulls in the paddock to try to solve our fertility problem.
"We're just really waiting in anticipation to see what's going to come out of those eggs, whether we're going to have calves with feathers, or whether we're going to have emus with horns and a hump, we don't know."
