We have 4 Jumbo Pekin eggs that are now 2 days overdue. Yesterday morning, we got our first pip, but it was at the wrong end! There was also bruising on two of the eggs (this one and his neighboring sibling) We waited 12 hours with no progress, so we decided to try to help. We chipped some of the shell away from the area and widened the hole that he made in the membrane. We left him for the night. We checked on him the next morning and STILL no progress. After some extensive research, we decided to help some more by chipping away the front portion of the egg where his beak is. We waited. Still nothing. So, on hour 36, we decided to pull off the outer membrane where his beak was and pop the TOP of the egg off, in hopes that he could rip his way out of the membrane. We then wet the outer membrane down with water, and could clearly see large veins where the air sac is supposed to be. He seems like hes strong. His breathing isn't labored, its quite consistent. He's chirping, but not as if hes in pain. Just as a response to our voices/quacks. We put a wet paper towel over the back of him, being sure not to cover his beak. I need advice. We are heartbroken because of how helpless we feel. This is our very first brood. I know that we are playing the waiting game, but any tips would be appreciated. Thank you in advance. .
