Hello, I’m new to backyardchickens and new to hatching. I am currently panicking. I set eggs on 9/24. On Sunday evening, 10/13 with one surviving embryo; I set for lockdown. When candling, embryo was doing well and had beautiful healthy veins but appeared to be in the small side. Hatch date to be expected on 10/16, I gave a few more days since it appeared to maybe have a delay in development. I haven’t seen any rocking or heard any chirping so very early this morning I decided to candle and see if chuck was alive or dead. The egg appeared very dark, hard to make out any veins and the air cell grew huge and lopsided down the side of egg. Didn’t see any movement and it wasn’t looking good so I chipped away at air cell area, (which had a peck mark and cracks that were repaired with candle wax) and the air cell just crumbled apart and is now very wide open at this point. It revealed the outer membrane that appeared to be very dry and white, I dampened it and could see the inner membrane full with red veins and low and behold I can see movement. So I am sitting here panicking and believing that I have ruined the chance for my sole surviving egg. I have upped the humidity to about 80% and I applied a very light layer of coconut oil to outter membrane. I would appreciate any advice! I am so worried and upset.
