I have 10 in the incubator that are ready to hatch and 8 more that are on day 12. So like an idiot I opened the bator to turn the 8 and I saw a huge pip in one of the day 24 ones - the sack was ruprured and I could sorta see inside. I closed as quick as I could when I realized it. But this morning there was no duckling and when I looked in the hole there seems to be a perfectly formed, but dead, duckling.
There are several other eggs with pips that have not broken the shell.
What (if anything) can/should I do?
