Our first chick hatched during the early morning hour Sat then Sat during the day 3 more followed. Sunday 2 more hatched. My broody still has 3 unhatched eggs under her and today is day 22. 2 EE eggs and one BC maran. I candled the 4 blue eggs at day 15 and they looked great, so I don't know why the last 2 blue eggs haven't piped. I don't know what's going on in the BC maran egg because it's so dark. So to sum it up, She has 2 EE chicks and 2 EE eggs, 4 BC maran chicks and 1 BC marn egg under her. The 3 remiaining eggs haven't piped. Should I chip at the shell a little, or is all hope lost?
