A bold red circle? If you see any veins, stop what you're doing and put the egg back in the incubator. It's very easy to damage those vessels and the chick can bleed out and die if you hit the wrong one. During the hatching process there is a lot of active blood vessels in the membrane covering the chick, along with the yolk sac that the chick needs to absorb before it can complete the hatch. These vessels supplied the chick with oxygen until now and the yolk is it's "food" for the next 3 days. This absorption process usually takes a few hours, some take up to 20+ hours, so please don't help unless it's been 24 hours or the chick shows signs of being in trouble.
