I live in Hawaii where we have wild chickens called "jungle fowl" which roam all over. They were brought by ancient Polynesians when they came to the islands.
There is a hen that comes to our shed and lays. She's neat and tidy and doesn't bother anyone or anything, so we let her nest in there. I go into the shed every afternoon and take out the single cream-colored egg that she lays. I leave a golf ball behind to encourage her to keep laying there. The problem is that when she's done laying her clutch of a dozen or so, she will brood on that last egg and it's almost impossible to get her to stop setting. I can take the egg and the ball, but she will take something from somewhere in the shed (like a small piece of PVC pipe or a u-bend) and put it in the nest and set on it. There's no way to shut the shed.
So once we go through this weeklong battle of her stealing stuff to set on and me taking it away, she finally stops being broody and leaves for a month. Then the next month she comes back and lays another clutch.
Is there a way I can keep her from going broody in the first place and just keep her laying coninuously? I don't want to handle her too much as she is wild and shy of people. I don't want to scare her off. I do feed her kitchen scraps.
