Should I help?

My broody buff Orphington started laying on I fertilized eggs, so I got her some to hatch. One out of nine did hatch, but then she started pecking and attacking it, so we separated the chick and left her the rest of the eggs to try again. Then, she abandoned the rest. I didn't have an incubator, so I just put the eggs under the brooder light and didn't expect much. One pipped overnight! I cleared it a little bit bigger hole and have been watching her all day. But I'm worried that I got a bit too excited and removed more she'll than I should have. She hasn't made any more progress on her own. She's chirping but making no attempt at getting out. I wet the membrane several times today and have the shell wrapped in damp paper towel under the light. In the morning, it will be 24 hours. Should I help remove more shell then? Seems to still have yoke under the membrane. I rewet the membrane and put some antibacterial ointment on it too. I will post pics when I figure out how. This is so anxiety inducing! I just want her to live and be healthy.
