I see a lot of people who sell hatching eggs, say that they're checking for egg fertility and expect it to go up because it's getting warmer out.
Are roosters less fertile in the cold? Or, maybe the embryo dies easily at low temps? If this is true, what temps are needed for higher fertility rates?
Thanks for any input.
