I am on day #21 with my 11 BCM eggs. One popped off a quarter sized piece of shell all at once ~4 hours ago. Most of the membrane is still intact however. It poked a small hole through the membrane with it's beak and his beak is all the way out and he is chirping. There is a large area of intact membrane and I can see the membrane pulsating with his breathing. He doesn't seem to have the ability to get any farther and since his beak is out, I'm not sure how he will cut the rest of the shell. The membrane is drying out and is turning yellow. When do I help? I know I am not supposed to help at all, but I have heard others comment that the BCMs do sometimes need help because their shells are so thick and hard to break through. My Barred Rocks are pipping and zipping and seem to be doing what has been described. Any suggestions???
