unhatched duck muscovy eggs

[TX homesteader]

2 of my female muscovy duck layed eggs around june 15th. they still haven't hatched. I wanted to ask because the weather has been above 100 degrees for the must of the summer have they died?

You said the eggs were laid in June. Are the hens actually sitting on the eggs or are they in an incubator? Do you have a drake? Do you know how to candle eggs?

If eggs were set on June 15th they would be very extremely rotten. Eggs just sitting in a nest for that long will also be bad.
