Ehh don't beat yourself up. My recent hatching started with 22 eggs and I only got 3 chicks total. I went to through 4 different sources. 2 of the sources are people I've bought live birds from and have complete trust in, yet none of their eggs hatched. Ironically, the other 2 sources I didnt know at the time, but did have some hatch. Those 2 where an Ebay seller and

I was rather let down at first, but I was also very naive about it all. I can tell you this though, I've learned alot in the last 3 weeks. Enough I didn't even have the incubator turned off for more than an hour before setting 18 more eggs.
One of the things I did was waited till and egg stunk before removing it. Even the ones I was 95% sure where not fertile. Even those eggs helped me learn. Like... Never let a none fertile egg that's been in the incubator for 14 days break in the house. Talk about a gag worthy smell!
I would suggest being cautious with Ebay eggs, but I did have success with the ones I bought, and the 18 I have now are from the same person.
Being naive is not always a bad thing. As long as there's something you can take from it, then it's education. I'm not calling you naive by the way, I'm talking about my own experience. However in regards to your situation, don't let it put a bad taste in your mouth. Although I only got three chicks, I had so much fun watching those three chicks it was worth it all. Maybe not financially, but educationally, enjoyment wise, the social aspect that it brought on. All of it was worth it. And who know, you might actually have viable after all!
