One of my hen is sitting. Since I have them in my backyard with NO rooster, she is wasting her time. I have read about putting the broody hen in a cage for a few days without bedding but water and food, of course. If I do that, can I leave her with the other girls outside and put her in the garage at night? or what should I do? Which system did work for you? I have a small backyard with 3 hens free ranging. My front yard is patrolled by cats and who knows what. Thanks a lot.
