How cold is too cold to collect eggs for hatching?

How cold is too cold to collect eggs to hatch? Its been in the teens to the negatives. Will they be ok to put in the incubator with it being that cold outside while they were laid?

How often do you get outside to collect? How warm is it in your coop during the day? Do you ever have frozen eggs? As long as they are not frozen, you have nothing to loose. I'd collect a clutch of eggs, and when there are enough to incubate (no more than 7 days old for the best hatch rate), I'd start them. The proof will be evident when you candle them at day 7 - day 10. If they're duds, you can try again. Certainly it'll be warmer by then.

The coops are whatever the outdoor temp is, but I do not believe any of the eggs have been frozen.
