Today is hatch day. I have had to help two eggs already as the membrane had totally encased them. The gap between the egg and the membrane was huge. So far the chick are ok. I opened the pip area carefully for the next one so it can breath. Any idea why this is happening. My humidity is at 72% and I have had to fight to keep it over 70% but I read the 60s should be ok. Any other idea why the membrane would encase all of them? I is born and 3 are in various stages. I think I opened the pip spot too late for one sadly.
