I have no rooster. 2 of the hens, BO and White Leghorn have gone broody and been that way for about a month now. I remove the eggs everyday but they still stay in the nest box pretty much all day and are not laying. Is there a way to get them to stop this since no eggs will hatch of course with no rooster? I read to dunk them in cold water to lower the body temp and tried that today and that worked for about an hour and I just went out and they were back in the nest boxes. Any advice?
