Have any others pipped yet. If not take them out and quickly candle them. Im not going to tell you to take them out and open they shells, but im also not going to tell you to leave them alone. 
I hatched out yesterday 11 on their own, 5 had zipped 2 hadnt pipped. I took the tops of the eggs and peeled back the membrane so they could push them selves out. The 2 that hadnt pipped I opened the shells. 1 had died and 1 was alive and shrink wrapped so I peeled the shell and outer membrane, sprayed the inner membrane, no veins so popped him out. All of mine were out in 5 hours, minus 1!! Its up to yoiu guys what you want to do. Me!!! I go with my heart and head, I dont wait to see IF they are goin gto hatch...they ARE going to hatch.
