Blach! I don't like the little red veins either.
How long have they been sitting there?
Of course, this thread says you posted over an hour ago.
I would be tempted to get some tweezers and pull/rip back a bit of the membrane so more of the beak is out.
Watch for any red capillaries, don't rip there, and go slow. I would keep going so that the entire beak was out so I knew the chick was breathing, en leave it for a few hours wrapped in a damp paper towel in a high humidity incubator. Do make sure there is no water right over the beak, don't want to drown it.
The problem is that the wiggling and hard work that the chick does is also what gets the blood to dry up and the belly to close up.
After I could see the beak, and I knew it was breathing, I would leave it alone for 12 hours (not eating and drinking but cramped in a shell is just fine really). Then after 12 hours I would reevaluate.
Good luck!
