72% is too high? I had 14 other chicks hatch out perfectly fine. I think the problem might've been that they were the last to hatch. I saw both of the curled toed chicks start unzipping last night. They finally hatched out this morning after I decided to help them. They had both unzipped but couldn't quite get out. I think they were both malpositioned/ had spent too long trying to get out. They both look fine aside from some curled toes.
For the cup method, I just put them inside a cup and put back in the incubator? For how long? I already took one of them out. The other is still inside the incubator drying off.
I've given the one I took out some electrolyte/vitamin water. I also just took off the "booties" because it seemed like they were causing it to develop splay leg.
