OK I'm new to this chicken keeping stuff. I've raised 9 chickens from day olds and now would like to experience hens hatching their own babies. How does this work? Do you leave eggs in the nest for a while and encourage hens to go broody? My silkie always hangs out in the nest box but not all day just a few hours. So once my hen goes broody can I then order eggs from my pet chicken or do I need to already have the eggs on hand? I have a rooster but I wanted to add some more silkies to the flock. He is a copper Maran mix. What else do I need to know? Will hens in a nest box overheat in the hot Alabama temps?
