Brown spot on white egg at pip site (duck)

[bwhitley4936]

I have 9 duck eggs in the process of hatching. One has externally pipped...the white egg shell has a brown spot around the pip. The shell is just popped up a little in a spot...membrane is not visable. I guess maybe knicked a blood vessel during pip? A couple of the other eggs that have not externally pipped have a brown spot on them as well. Could this be an indicator that the duckling is attempting to pip in that spot?

Where are all you incubating/hatching gurus!?

Same issue how'd it turn out for you??

If it kinda looks like a bruise, that's normal for my hatches
