I do check under hens when they are on eggs, but I've never had an issue with babies being shrink wrapped before; when I last checked, none of the eggs under her were pipped. Nothing was different than I've done before. She has one more egg, and I have several newly hatched chicks from the incubator that I am going to try to give her. Just frustrating to encounter a problem that I've never had with a broody before.
