Just wondering what others' experiences have been with egg fertility after the rooster is no longer in the breeding pen. I have a young hen that's been away from the roo for twelve days. I keep plopping her eggs in my 'bator, and the eggs she's laid up until three days ago appear to be fertile. Can't tell about yesterday's or today's eggs yet, obviously. I have always been under the impression that a hen can "store" the rooster's...um, essence...for three to five days. Anyone have any input on how long a hen might continue producing fertile eggs after the rooster has been removed from the picture? Thanks!
