I have a hen that has been sitting on like, nearly 30 eggs (its a long story
). The first one hatched yesterday. A second one several hours later, and a third this morning. I don't see any other pips. How long do I let her keep sitting on those eggs? How do I know when I can start chucking duds? How do I know they're duds, and do I remove them and stick the non-duds in an incubator after letting her sit a while longer?
