I don't really know the answer to your questions, but are these the eggs that were crossed with the marans? Marans can be notoriously late to hatch. I have never had any luck helping chicks out if they are not already pipped. Also, if they were in a styrofoam incubator sometimes the temps are not quite even and some may be later than others.
Maybe someone else can give you better advice.
Congratulations on your first hatches!
Which ones are hatching? Any of the ameraucanas hatching yet? If any of the crossed chicks are hatching, what do they look like? You know we have a rule here you have to post pics of your fuzzybutts!
