We lost power to our incubator

Today at 4 am our power went off and it did not come on until 12 noon.
In the 8 hours the temp dropped to 80 degrees.  Our eggs have been in
the incubator for 9 days.  Are they ruined?  We only have 10 eggs in
the small incubator and we are only hobbiests so, would it be better
for us to toss the eggs and start over or should we keep them going
for the remainder of the 21 days?  THanks for any advice.
