Had a duck do this to me.. 12 call ducks.. I had to raise them myself. That was an experience.. a very smelly experience.. Never again will I raise that many ducks without a broody!You could brood them yourself if that makes you feel better. I would hate to tell you that you should keep them with her, and then have her hurt them. It sounds a little like she might be distracted by the other hens, so maybe if you brought them all inside (if that's an option for you) she might pay more attention to the babies. Sometimes broody hens realize they don't actually want babies until they have them. One of my broody hens sat on eggs for all 21 days and then decided she was done and wanted nothing to do with motherhood. I don't want this to become a huge ordeal for you, it might just be easier and less stressful if you brood them.
