We have a broody hen. We bought her 6 fertilized eggs online. She's been perfect for the full 22 days. We haven't candled, moved or really even messed with her eggs. Not because we didn't want to but because she didn't let anyone near her. I have seen them and they are clean and unbroken. When should we start to worry? She's been nesting in common space. Do I have to worry about the other hens. We only have 3 others and we have never had any issues. Thank you for your help. We are very excited for our new little ones. What are our chances of any hatching? It is her first time.
