My hen is staying on the eggs, she is even biting me when I tried to check how many new eggs and to mark the new ones. She is an Easter Egger, they may be geared to go Broody. But it seems I was able to make one of my girls go broody by locking her in with 5 eggs and 1 of her own. I actually didn't start with her, I tried this with another of my girls and she was not having it, she didn't sit on the nest and she would only roost and she didn't like being locked in the nest house. Then I switched hens and this second girl the first night did not stay on the eggs and she chose to roost, the second day after laying her egg she chose to stay on the nest, and this third day I noticed she got up for a few minutes to move around and eat and drink then moved back to the eggs. I think isolating her from the other girls helped me get the results I am.
