I totally understand as it can be stressful, especially at this point. If there is no active veins in the membrane and it's not chewing/yawning, it might be unable to zip. At this point, I open up the entire area over the air cell. You still don't want to pull the little from the shell, you'll want to let it do that and oftentimes I find that frustration you're hearing is just what they need to push out. Once the shell over the membrane has been removed, you should be able to get a better idea if he's stuck or not. What has your humidity been?I just moistened it. And I turned up the humidity to 70%. No veins or membranes at all. I’m so worried!!
