Found something on my egg yolk

[GoofyNewt]

I was about to make scrambled eggs but one of my duck eggs had this attached to the yolk I'm not sure what it is the egg is no older than 4-5 days is it safe to eat and what is it

It appears as though some fecal/foreign matter got incorporated into the egg durning/prior to the shell being laid down.
It happens occasionally.

Really?
I guess it's more apt to happen with ducks during mating?


I would not eat that egg...and it would have me breaking eggs one at a time in separate dish for quite some time.
