Can shipping affect the fertility of eggs? I purchased two dozen eggs. 12 Brahma and 12 Barred Rock (received 19 BR). I waited 24 hours before incubating because they were shipped. I checked on day eight and only 5 Brahma and 14 Barred Rock eggs were fertile. Seems really high that a dozen of 31 eggs weren’t fertile so thought I’d ask about possible causes other than being send unfertile eggs. Thank you.
