Okay, you can probably tell I'm new at this. I can't get my hens to sit their eggs. I tried building roosting stations and the hens broke and ate their own eggs. They had plenty of feed and water. My grandmother said chickens hatched in the machine won't sit their eggs. Any truth to this and what do I do to get them to hatch their eggs? I tried putting their eggs in the duck nest but the ducks kick them out.
