Can you incubate eggs that have been sitting at room temp (70-74) for several days?

My daughter has a science fair project and my source of eggs ran out so I need to use mine. Since I wasn't planning on using them they have been sitting on the shelf and I need to use 50 at the very minimum.

Will we have success in hatching these?

I've read people have eggs shipped and eggs outside aren't historically kept at a low temp. My incubators are ready and they won't need to rest so I just want to make sure and not waste them.

Some would undoubtedly hatch but possibly not as many as would hatch if your storage temperature were a little lower.

I found this in a university extension service publication (https://alec.unl.edu/documents/cde/2017/livestock-management/incubating-and-hatching-eggs-2017.pdf) :

"Temperature and humidity during storage

Fertile eggs should be stored between 55 and 65°F. If fertile eggs reach temperatures above 72°F, embryos will begin to develop abnormally, weaken, and die. Embryos stored below 46°F also have high embryo mortality. Room temperature is generally too warm and the refrigerator is too cold for storing fertile eggs."

How long have they been sitting. It's totally possible!

We ended up finding the 50 we needed from another chicken family and we are 8 days into incubation. We candle in 2 days to find out how many are so far successful
