My BO hen was just on the nest for 3 1/2 weeks trying to hatch golf balls and infertile eggs. She refuses to leave the nest and hops right back on when I remove her. She seems very determined to hatch something - anything. When I moved the golf balls to another nest, she stole them back. My other hens are quite happy to lay eggs in her nest, and she is happy to set on them. We do not have a roo. I do have fertile duck eggs, but my ducks are not broody. My question is: since she wants to stay on the nest and keeps trying to hatch everyone else's eggs, do you think she will set for another 4 weeks on duck eggs? Or should I try to break her brooding and let her rest for a few weeks? She feels rather thin to me and I was feeding her at the nest, but I don't want her to get sick or lose more weight. Should I go along with her and let her hatch ducklings, or try to break her broodiness?
