Well, I bought twenty eggs off eBay the beginning of this month. I put them into a band new HovaBator Genesis 1588 with an automatic egg turner. I kept them at 99 degrees and about 40 to 50% humidity for the first 18 days and then took the turner out and raised the humidity to about 80%. Yesterday day was day 21 and only one chick hatched. There are no signs of any of the other eggs hatching even now. So, now I am questioning whether I did something wrong or if buying eggs off of ebay just does not work. These eggs are from a special breed of chicken and ebay was the only place I could find any. These twenty eggs ended up costing me $116 after shipping fees. I did not expect a 100% hatch rate, but only one out of twenty has me pretty upset. What do you think? Did I do something wrong in the incubation? Are eggs off of ebay just unreliable or a scam? Could some of them still hatch even though it's been 22 days? Thanks for the help.
