I've been incubating Domestic Malards for a about 4-6 months. All have died during hatching or died prematurely. I have one that has magically survived. It pipped yesterday morning and started to zip that night but didn't finish. It is still breathing and moving. While its in a regular position, I checked on it a few minutes ago and noticed it's claw/foot was coming over and laying on top of its face. I would assist with that part but there is still one noticeable vein showing and I don't want to assist prematurely and have it not survive. What should I do? Or should I leave it be?
