The rocking egg chick is nearly out, but in all that time the other 2 eggs have not progressed. One has not changed at all, and the other has removed about another 3-4mm of shell from it's little hole and then nothing for a few hours. Should I be worried about these 2 eggs? And none of the other eggs have started to do anything yet. I had 4 leghorns (all fertile, I started with 6 and discarded 2,) 6 legbar (all fertile) and 6 maran (too dark to tell.) The eggs which have pipped but are not progressing are maran eggs, and the rocker is a legbar. Today is day 21. Any words of wisdom? How long should they take to hatch?
