I had shipped eggs that I tried to hatch under a broody last year. They came in the mail scrambled. Out of 18, I set 7. They were gooey and had loose air cells. I had nothing to lose. One started to pip. I left it alone because everyone said it is bad to help. Let nature take it's coarse. Well, it died at the pip. I had another one pip the next am. I helped her. I was very careful, using tweezers and moist papertowels and a heating pad. I tried to do as little as possible, but she was just too weak. I tried placing her back under "mama" who then kicked her out. (I made the mistake of giving her silkie chicks, when the shipped eggs weren't hatching. Finally ended up keeping her warm in the oven until she dried off and I could put her in a brooder. "Lucy" is my one and only SLW. She's beautiful. I call her my $20 chicken.
DH says we can't butcher a $20 chicken, so I guess she's safe.
From my experience, I would help again.
