White/Yellow goo attached to chicks back?

[lmadeline146]

It’s day 21 and I’ve had 4 chicks hatch so far, but one came out with some stuff on it’s back still attached in the image below. There was no blood, but I don’t want it to dry and get crusted in his/her feathers. What should I do? We still have multiple chicks pipped.

Just the left over egg goop, you can either take if off now or wait as it will fall off eventually as the chick dries and fluffs out. Just be sure you do not tear off anything attached to the belly of the chick where the umbilical cord is.
