Yellow sticky substance oozing out of pipped egg

[Rookie15]

I had my humidity at 50% until lock down then it’s been at 70% for hatching. Nose and mouth are clear. I moved him to his own incubator and seems to be doing good in there still. Was going to wait until those blood vessels absorb and maybe assist his hatch as that yellow fluid dries rock hard I’ve had 4 others hatch today and non were like this

Have a similar situation now. I'd love to know your further interventions if needed, and outcome.
