What's hanging off new hatchling?

[BuckleyChick]

First time with a hatchling and I came home to find this little one with something hanging off it. What is it? Should I be worried? Do I need to do anything.

Breed: Olive Egger/Silver Wyandotte

No other hatchlings in incubator

Just some hatching gunk, or embryo wastes from while the chick was still in the egg. It should fall off on its own, but if you want you can gently wipe it off.
Congrats, it's adorable!
