Really? Are you sure they were the kind that says "fertile" on the box? They look the same as the organic or free range (can't remember which) but they say different things. Has to say fertile on there. I have had really good fertility both times I did this. Also, make sure you get them as fresh as possible. The eggs are dated with the Julian calendar date, so today is day 298 (the 298th day of the year) You'll want to get as close to that date as possible, so something around 290 would be ok. I've heard some people got them within 4 days, but I don't think you'll get much closer than that Maybe give it another try?
