I had a chick start pipping early this morning after work it hadn't progressed but egg was still rocking. later in the night I lost power for a little over an hour I put a propane heater next to bator which managed to keep the temp up above 95. but I didnt know how much the humidity dropped. when the power came back on it was in the 30s. I waited a couple more hours but still no progress so I widened the pip a little to see in. it was shrink wrapped. so I removed some of the shell and pushed some of the membrane back so she can breath wrapped her in paper towel and put her back in the bator. after I put her back in I noticed 2 more eggs had pipped sometime in the time it took me to help her. I have the humidity up to 70 and it seems to be keeping her inner membrane clear and damp. so I'm hoping that the other chicks membranes are good as well. if anyone has advice for this it would be appreciated.
