So can I just go out to my coop and grab some eggs and put them in incubator? It is in the 20's outside right now. Do I need to wash them or pick really clean looking eggs? I
If the temperature is in the 20's and the eggs have been out there for a few hours they probably won't hatch. If you collect them and they have not been out in the cold for a long time they probably will hatch as long as they are fertile. Usually fertility goes way down during cold or hot weather. Maybe break open an egg and check it for fertility. Don't wash they eggs. If they are quite poopy you can brush off the poop but don't wash the eggs.
