My hatch finished yesterday - I had 2 eggs that were developed but did not pip. I listened to them but they did not make any noise at all. Today was day 22/23 - not exactly sure. I opened the air sac end and could tell the chicks were dead as there was no movement at all. I continued to open the egg and remove the membrane - I was wondering if someone with much more experience could look at this picture and give me an estimate of the chick's age? Did they die at 15 days? 18 days?
