Eggs which have been subjected to freezing conditions (in the coop or in shipping) will have suffered damage to their internal structures and are highly unlikely to hatch. Incubation during this time of year due to the temperatures will have to occur indoors with a stable temperature.
Beside this, Can you hatch eggs that have been in the fridge?

Also, How long can incubator stay without power?
Some embryos can survive at temperatures below 90°F for up to 18 hours, so do not give up. You should continue to incubate the eggs after the outage; then candle them 4 to 6 days later to see if there has been further development or signs of life.
How cold can an egg get and still hatch?
Eggs kept above 27°C (80.6°F) will start to develop. However the development will be disproportionate with some parts of the embryo developing faster than others and some organs may not develop at all. Below 35°C (95°F) no embryo is likely to survive to hatch.

What temperature will kill chicken eggs?
The acceptable range is 97° to 102°F. Mortality is seen if the temperature drops below 96°F or rises above 103°F for a number of hours. If the temperature stays at either extreme for several days, the eggs may not hatch. Overheating is more critical than underheating.
Can you hatch an egg from the grocery store?

Will eggs hatch at 102 degrees?
Perhaps the most important parameter is temperature – chicken eggs should be incubated at a temperature between 99 and 102 degrees Fahrenheit (99.5 is often considered to be ideal) and 50 to 65 percent relative humidity (60 percent is often considered the ideal).
Will eggs hatch in cold weather?

How can you tell if eggs are fertile before incubation?
