Keep the chick warm and hopefully they will adsorb what is hanging out or it will dry up and fall off in a few days. Don't let other chicks peck on it as that could pull out the rest of the internals. Sometimes it happens when they pop out a bit early or if heat in the bator was a bit high. Doesn't look bad at all though. Just let the chick rest and it should turn out fine if it doesn't have other developmental defects. Best of luck.
