How long have they been in lock down?
what day are you on?
I am going on 22 days. So I probably should not worry. But the shipped eggs have terrible saddles. a couple going along down the side.
My d'uccle that pipped hasn't done anything for a couple of hours. And now there is a small brownish red spot on it outer membrane.
I guess, I got over excited, cause my last 2 hatch went so great. But those were all my eggs.
