Will eggs left in the cold weather before collection still hatch?

[acemario]

So I am going to start collecting eggs to put in the incubator in about a week, however, I am unable to collect the eggs until I get home from work around 5 pm. Will the eggs still hatch if they are left in the nesting box in the 20 degree weather?

I tried to find relevant posts, but to no avail.

They might, and they might now. It is worth a try to see though!
